27 Best JavaScript Frameworks For 2024

When searching for best JavaScript frameworks, you’ll encounter a plethora of options, each with unique advantages and applications. The abundance of choices, spanning front-end, back-end development, and testing, can make it challenging to select the ideal JavaScript framework to suit your needs.

According to Stack Overflow Developer Survey 2023, JavaScript is the most commonly used language for the 11th year straight, with 54.45% of people opting for it. The major reason for its popularity is that JavaScript is versatile and can be used for both front-end and back-end development and for testing websites or web applications.

In this article on the best JavaScript frameworks for 2024, I’ve come up with a list of the best JavaScript frameworks for front-end, back-end, and testing, which might help you with this.

11 Best JavaScript Frameworks for Front End Development

JavaScript has been widely used for front end development for almost 2 decades. Popular frameworks such as React, AngularJS, and Vue.js are gaining and losing a legion of followers but still manage to rank top in best JavaScript frameworks, while few new competitors have been gaining ground recently to challenge the big 3. As per the State of JS 2022 survey, here are the 8 best JavaScript frameworks for front end development in 2024.

1. React

React, also known as React.js, is one of the best JavaScript frameworks in the front-end category. It is an open-source front-end JavaScript library created by a team of Facebook developers led by Jordan Walke back in 2011 and became open-source in June 2013. The initial prototype was dubbed “FaxJS” and was first experimented with in Facebook’s Newsfeed. React can be considered one of the biggest influential disruptors in the web development domain that delivered a real breakthrough in shaping the web applications we see today.

React introduced a component-based, functional, and declarative programming style for creating interactive user interfaces for mainly single-page web applications. React delivers blazing-fast rendering by making use of ‘Virtual DOM.’ DOM stands for Document Object Model, which renders only those components that have changed instead of rendering the whole page. Another key feature of React is simpler JSX syntax instead of JavaScript.

Although React presents a slightly steeper learning curve than other best JavaScript frameworks in this list, it is supported by a huge developer community, bountiful learning resources, and massive industry adoption in every corner of the world.

React Usage Statistics:

• As per the State of JS, it has been ranking 1st in the list of front end best JavaScript frameworks worldwide for the 7th consecutive year! React has polled 1st place since 2016, ahead of mainstream rivals Vue.js and AngularJS as the best JavaScript frameworks.
• 81.8% of JavaScript devs are currently using React.js, whereas an additional 47.2% have shown a keen interest in learning this JavaScript framework in the future, as per the State of JS 2022 survey.
• With 40.58% of the vote, React surpassed jQuery to claim the second spot in Stack Overflow Developer Survey for best JavaScript frameworks in 2024, leaving it in the third spot.
• Current version – 18.2.0
• GitHub – 220k+ Stars and 1,651+ Contributors.
• NPM – Averaging close to an all-time high of 25M+ weekly downloads.

Pros of Using React:

• Reusable Components – Its component-based approach helps developers import or reuse UI components without breaking a sweat instead of coding them from scratch.
• Easy Integration – Allows easy integration with other front-end and back-end frameworks like the popular PHP framework Laravel to work seamlessly without a hitch.
• Direction Dataflow – The main difference is React.js follows a downward directional data flow architecture. This ensures that a child element cannot affect the parent making the code more stable and less prone to errors.
• Simpler Syntax – Uses JSX JavaScript extension instead of usual JavaScript, an HTML-like syntax that makes the code easier to read, understand and maintain.
• Virtual DOM – Creates a virtual representation or a copy of DOM called Virtual DOM or vDOM. React compares the virtual DOM to the real DOM to only render components that have changed instead of rendering the whole page. This is the key behind React’s blazing-fast performance.
• SEO – After many improvements, React.js is one of the most SEO-friendly front-end frameworks that facilitate page crawling. Traditional JavaScript frameworks that rendered content dynamically were notorious for their poor SEO performance and incompatibility with search engine crawlers.
• Continuous Improvement – React is in a state of constant evolution and improvement, adding key new features like Hooks, Fiber, Concurrent Mode, Suspense, etc., for reducing boilerplate code, improving concurrency and fast rendering, and boosting performance, making it a strong contender in the best JavaScript frameworks category.
• Rich Community Support – React is backed by a massive Developer Community with almost 1.6k contributors on GitHub and a wide array of learning resources, tutorials, and help guides readily available to anyone starting. Also, do not forget React.js is backed by one of the world’s largest and most powerful companies– Facebook.

Cons of Using React:

• Although JSX is a simpler syntax that is easier to read and comprehend, it might present an additional learning barrier to new developers.
• Many developers might feel React has a much steeper curve and bloated complexity than key rival frameworks like Vue.js or any other best JavaScript frameworks.
• React is often plagued with complaints about poor documentation that cannot catch up with new releases and features, forcing developers.
• Deals with the View Layer of the MVC Model, leaving no option but to rely on other technologies to deal with Model and Controller Layers.

2. Angular

Angular is an open-source framework by Google for building dynamic single-page web applications. It uses TypeScript for type safety, leverages reusable components for structure, and offers two-way data binding for streamlined development, making it a popular choice for scalable web projects.

Angular Usage Statistics:

• Angular has ranked as the #2 for front end Best JavaScript frameworks in the State of JS 2022 survey for the 2nd consecutive year.
• In Stack Overflow Developer Survey 2023, Angular was ranked 5th for front end best JavaScript frameworks, with 17.46% positive response.
• Current version – 17.2.3
• GitHub – 93.9k+ Stars and 1873k+ Contributors.
• NPM – Angular registered a massive 3.5M+ weekly downloads on NPM.

Pros of Using Angular:

• Component-Based Architecture – After ditching MVW (model-view-whatever) architecture, Angular 2 and beyond adopted a strictly component-based architecture that facilitates reusability. Components can be used over and over again throughout the app. It also enhances code readability and ease of maintenance.
• Server Performance – Angular supports out-of-the-box caching and many features to ensure fast server performance.
• MVC – Model View Controller in angular establishes key features like scopes and data binding. It also ensures UI and App logic are isolated from each other.
• 2-Way Data Binding – One key feature of Angular is 2-way data binding, which forms a link between the Model layer and View layer in such a way that each one of them reflects a change in another. However, other rival frameworks have adopted a one-way data binding for simplicity.
• Third-Party Integrations – Angular offers a rich collection of third-party integrations to enhance their web application further.
• Massive Community Support – Angular is blessed with backing from Google and a huge developer community amassing over 1.6k contributors on GitHub. AngularJS also has great documentation, a huge library of resources, and community support.

Cons of Using Angular:

• TypeScript – To use Angular, you must use TypeScript, which offers many advantages but still poses a big learning challenge for new developers. TypeScript is a big barrier to entry and explains why angular has struggled against React and Vue.js.
• Heavy and Bloated – Compared to lightweight alternatives like React and Vue, AngularJS is extremely bulky and large, roughly close to 550-600kb, which might not be suited for most small-scale applications.
• Poor SEO – Angular struggles with SEO due to acute accessibility issues cornered with search engine crawlers/spiders. If SEO is your prime focus, React is a much better SEO-friendly alternative.

3. Vue.js

Vue.js or Vue is an open-source lightweight front-end JavaScript framework used to build creative user interfaces and high-performance single-page web applications with minimum effort.

Vue.js was first launched in 2014 by Evan You, a developer working for Google who took inspiration from AngularJS to deliver a simple, lightweight, and efficient alternative in the form of Vue.js. And since then, Vue.js has been one of the best JavaScript frameworks for front end development. Although Vue.js has adopted most of its features from ReactJS and AngularJS, it has made major improvements to those features to deliver a better, easy-to-use, and secure framework. The biggest example of this approach is that Vue.js offers a 2-way data binding, as seen in AngularJS, and ‘Virtual DOM’, as seen in React.

Vue.js Usage Statistics:

• Vue.js has been placed at #3 in the list of best JavaScript frameworks for front end in the State of JS 2022 survey by developers.
• 46.2% of JavaScript devs currently use Vue.js and pledge to keep using it, while 50.7% have shown keen interest in using it.
• Current version – 2.7.16
• GitHub – 206k+ Stars and 364+ Contributors.
• NPM – Vue.js registered an impressive 4.8M+ weekly downloads on NPM.

Pros of Using Vue.js:

• Simplicity – The strongest ace of Vue.js is its simplicity. Any React or AngularJS developer can pick up Vue in a heartbeat without breaking a sweat. The structure of Vue is simple and enables you to code more with typeless syntax. Vue uses a single-file component system, meaning that HTML, CSS, and JavaScript reside in a single file for any given component.
• Built-in MVC – Have inbuilt MVC that enables quick and easy configuration, unlike ReactJS.
• Easy to Learn – Does not require you to learn JSX or TypeScript like React or AngularJS. Vue uses easy-to-grasp HTML templates that do not increase the complexity of code.
• Small Size – Another key advantage is its surprisingly lightweight size, given its impressive prowess. The zipped version of Vue.js is barely 18-20 kb in size, much lighter than its bloated, bulky rivals like React or AngularJS.
• Integration – It cannot only be used to create applications from scratch at a blazing-fast face but can also be integrated into existing web apps seamlessly without any trouble creating new components.

Cons of Using Vue.js:

• Small Community – Vue.js does not enjoy the backing of a giant like Facebook or Google, like in the case of React or Angular. But Vue has indeed managed to create a community of backers. On GitHub, Vue has 360+ Contributors, which is decent but nowhere close to the backing React enjoys with 1.6k contributors.
• Limited Employment Opportunities – Vue is undoubtedly extremely popular in China and the US, but that might not be the case in the rest of the world. Traditionally the US is the leader in new technology adoption, with the rest of the world lagging.

4. Ember.js

Ember.js is an open-source JavaScript framework for building scalable single-page web applications for businesses. Model-View-ViewModel (MVVW) architecture is the foundation for Ember, unlike other frameworks we have discussed.

Ember.js was originally a SproutCore 2.0 framework that was renamed Ember.js by its creator Yehuda Katz, an accomplished developer credited as one of the chief creators of jQuery. One of the most adored and key features of Ember is the Ember Command-line interface tool, which is a productivity powerhouse. Such features make it one of the best JavaScript frameworks.

Even though Ember.js is an older front-end JavaScript framework compared to React, Vue, and Svelte, it still packs a punch and has a big user base with major companies like – Microsoft, LinkedIn, Netflix, Twitch, etc.

Ember.js Usage Statistics:

• Ember.js is ranked number 4 in the list of the best JavaScript frameworks for the front-end category in the State of JS 2022 survey.
• GitHub – 22.4k+ Stars and 824+ Contributors on GitHub.
• NPM – Ember is hovering close to 913+ weekly downloads on NPM.

Pros of Using Ember.js:

• APIs – Ember provides a simple mechanism to work with APIs.
• Convention over Configuration – Ember.js follows the “CoC – Convention over Configuration” approach, which ensures that there is no need for any configuration in most cases so that you can jump straight away to coding and building your web application.
• Rich Documentation and Support – Ember.js comes with detailed documentation, thorough tutorials, and help guides to help you get started easily.
• Ember CLI – The Ember Command Line Tool is a productivity booster that not only helps to set up new projects but also creates components and controllers using automatic generation. Ember CLI also helps to install 3rd party dependencies.
• Inspector Tool – Ember.js has an Inspector development tool extension for Chrome and Firefox that helps to monitor and edit applications in real-time.
• Supports 2-way data binding similar to AngularJS.
• Backward compatibility with previous versions.

Cons of Using Ember.js:

• Steep Learning Curve – Newbie developers might find Ember.js quite challenging compared to Vue.js or React.
• Highly Complex – Complex for large-scale applications and might be too bulky and heavy for simple small-scale applications.
• Highly Opinionated – Opinionated in the sense that any deviation from doing things in a standard way might lead to frustrating problems.
• Stagnation in Popularity – Suffered stagnation over the last few years, failing to attract new developers into its fold.

5. Preact

Preact is a lightweight, swift, high-performance library and alternative to React. Preact is merely 3kb in size (minified and gzipped) and yet gives you all the necessary functionality of React, making it one of the best JavaScript frameworks. Preact was created by Jason Miller, Senior Developer Programs Engineer at Google, and can be considered as a subset of React stripping away some functionalities.

Preact is built with the same core principle of React – A component-based approach with Virtual DOM while completely compatible with React. It can even use React packages without compromising on speed, performance, and leaner size. In instances where the full potential of React isn’t necessary, most developers even use React during development and switch to Preact for production. Many major companies like Tencent, Uber, and Lyft are using Preact.

Preact Usage Statistics:

• In the State of JS 2022 survey, Preact ranked fifth among front end best JavaScript frameworks.
• 9.5% of JavaScript devs polled have used Preact before and plan to stick with it, while 22.6% have shown keen interest in learning and using it in the future.
• Current version – 10.19.6
• GitHub – 35.8k+ Stars, 1.9k+ Forks, 311+ Contributors.
• NPM – Preact recorded 3M+ weekly downloads on NPM.

Pros of Using Preact:

• Smaller in Size – With its lightweight size, Preact still delivers a faster render performance compared to other JavaScript frameworks such as React and Vue, which has a size of 40-45kb (gzipped).
• High Efficiency – More efficient than React and other best JavaScript frameworks in memory usage. It means the garbage collector has to do less work.
• Preact CLI – Offers an extremely powerful command-line interface tool that helps you easily create new projects while saving you the effort of dealing with Babel or web pack.
• Link State Module – Even though Preact is a subset of React, it has few advanced features. The most important is the LinkState module that optimizes state changes. React that uses arrow functions inside a render() method to update state. This method is inefficient, with a lot of unnecessary code. Preact solves this problem by using the LinkState module that returns a handle function when passed in an event updates component state changes automatically.
• Compatibility – Uses the same ES6 API as React, so developers can easily switch to Preact from React in an existing project during production.

Cons of Using Preact:

• Preact does not support propTypes like other JavaScript frameworks such as React.
• Another big drawback with Preact is that it does not support createClass. It only supports stateless functional components and ES6 class-based components.

Prominent Websites Built with Preact:

Bluehive, Bustle, Dailymotion, Dev.to, Dominos, Financial Times, GroupOn, Hashi Corp, Housing.com, Lyft, Pepsi, Rocket Chat, Smashing Magazine, Synacor, Sogou Wenen, Tencent, Treebo, Uber.

6. Svelte

Svelte is an open-source component-based and one of the best JavaScript frameworks written in TypeScript. It was created by ex-Guardian front-end developer Rich Harris. Svelte was first launched in 2016 and has witnessed an absolute explosion in popularity.

Many developers consider Svelte a truly game-changing and revolutionary idea that fundamentally changes how we code web applications and are tipping Svelte to dethrone other most popular front-end JavaScript frameworks in the world.

Svelte, unlike other JavaScript frameworks such as React or Vue.js, has no virtual DOM. Instead, you build components boilerplate-free in simple HTML, CSS, and JavaScript code. Svelte Compiler then compiles this code into small framework-free vanilla JavaScript modules during build time and surgically updates the DOM when the state changes. So unlike other traditional frameworks like React or Vue.js, Svelte does not require high browser processing.

Svelte Usage Statistics:

• Svelte has managed to break into the State of JS rankings for the first time as one of the best JavaScript frameworks, almost 3 years after its initial release. Svelte ranked as the 6th most used front end JavaScript framework beating venerable competition like Ember.js, Preact, and other JavaScript frameworks.
• Current Version – 4.2.12
• GitHub – 75.7k+ Stars, 3.9k+ Forks, 554+ Contributors.
• NPM – Svelte recorded 0.93 million weekly downloads on NPM.

Pros of Using Svelte:

• Component-Based Model – Follows component-based models like Prominent JavaScript frameworks such as React or Vue.js. New, improved reactivity features in Svelte version 3 have made building reusable components faster and simpler by writing less code.
• Easy to Learn – With its gentle learning curve, and is arguably most suited for new developers. Reusable Components are built with simple HTML, CSS, and JavaScript code; no additional knowledge of TypeScript or JSX is required.
• Smaller in Size – Smallest bundle sizes among all other libraries or JavaScript frameworks as it has no bulky JavaScript framework runtime overhead and is simply a compiler.
• Excellent Performance – As stated earlier, Svelte does not have a virtual DOM like React; instead relies on reactive programming to surgically update the DOM. As a result, Svelte can achieve the fastest rendering compared to almost any other framework and tops most of the performance benchmarks.
• SEO – Unlike some other framework that struggles with search engine crawlers, Svelte is SEO-friendly.
• Supports Client-side as well as server-side rendering.

Cons of Using Svelte:

• Limited User Base – Even though Svelte has won critical acclaim and laurels in the developer community, it is yet to be adopted widely in the industry. Svelte.js does have a few big-name clients under its belt, but the number of websites running Svelte is barely 3-4 thousand, and that too mostly in the United States of America.
• Lack of Tooling – One of the biggest complaints against Svelte has been its poor immature tooling for debugging applications.
• Small community and resources compared to other best JavaScript frameworks.

Prominent Websites Built with Svelte:

7. Backbone.js

Backbone.js is a JavaScript-based framework that connects to an API via a RESTful JSON interface. Backbone.js is known for being small and light because it only requires jQuery and one JavaScript library, Underscore.js, to use the entire library.

Jeremy Ashkenas, renowned for creating some of the best JavaScript frameworks, such as CoffeeScript and Underscore.js, launched Backbone.js on 13 October 2010. It is intended to create single-page web applications and maintain synchronization between different web application components, such as numerous clients and servers.

Backbone.js Usage Statistics:

• Current version – 1.6.0
• GitHub – 28.1k+ Stars, 5.4k+ Forks, 326+ Contributers.
• NPM – Backbone.js recorded 0.63 million weekly downloads on NPM.

Pros of Using Backbone.js:

• Backbone.js assists programmers in structuring their code in a more logical and scalable way utilizing the MVC (Model View Controller) pattern, making it simpler to debug and scale the application over time.
• Due to its minimalistic approach to providing the fundamental framework for online applications, Backbone.js is considered lightweight. A few kilobytes in size, its core library only contains the models, views, collections, and routers necessary for creating web applications.
• Backbone.js encourages developers to break down large systems into smaller, reusable components emphasizing modularity. As a result, the development process can be streamlined since each component can be created and tested separately before being incorporated into the main program.

Cons of using Backbone.js:

• Developers might need to integrate extra libraries or write custom code to do certain jobs, so developers may need to handle more complicated activities.
• Backbone.js’s basic approach can be challenging for developers new to web development because it necessitates a solid grasp of JavaScript, HTML, and CSS.

8. Alpine.js

Alpine.js is a robust, understated framework for adding behavior to your markup. Consider jQuery for the contemporary web. Start by inserting a script tag. Alpine.js comprises 15 attributes, six properties, and two methods, making it the most minimalistic JavaScript framework. It is created by Caleb Porzio, also the creator of Livewire.

Alpine.js is one of the best JavaScript frameworks that seek to give vanilla JavaScript some of the advantages of JavaScript frameworks, like responsiveness and composability. It offers a straightforward syntax for handling state, specifying components, and updating the DOM.

Alpine.js Usage Statistics:

• Because of its minimalism, Alpin.js’s awareness gradually increased from 38% in 2020 to 52% in 2022. And 33% of developers have shown interest in using or learning Alpine.js.
• Current version – 3.13.6
• GitHub – 26.4k+ Stars, and 1.1k+ Forks.
• NPM – Alpine js recorded 132k weekly downloads on NPM.

Pros of Using Alpine.js:

• Alpine.js is a fairly potent front-end library that enables users to create declarative responsive interfaces. Alpine is typically used to add additional directives and JavaScript injection to static HTML templates to make them interactive.
• Alpine.reactive () and Alpine.effect () are responsible for causing reactivity, but these functions utilize Vue.js’s reactivity engine. This powerful engine may be used independently or as the foundation for abstractions.
• There are many parallels between Alpine.js and (front-end) Vue.js, but the Alpine method for designing interfaces is a bit cooler to work with. For example, It does not require < template > wrappers, and with Alpine.js, you can directly wrap component data in HTML, which improves functionality.
• Even while Alpine.js is not intended to be a native full-stack interaction tool, asynchronous activities involving data fetching from a server are quite common and crucial from a templating standpoint. You may download data directly from the Alpine.js template by explicitly designating a function handler as an async or doing the inverse.

Cons of Using Alpine.js:

• It offers a simple syntax for developing UI elements and dynamic web apps, although it could not have all the capabilities and functionality of frameworks with more features.
• It has a smaller community than more well-known frameworks, which could make it harder to get help and resources.

6 Best JavaScript Frameworks for Back End Development

One of the key reasons behind JavaScript’s wild success and its ascend to the throne of the world’s most popular programming language is its versatility. Not only can JavaScript be used for client-side front-end development but server-side back-end development, thanks to Node.js.

There are several server-side JavaScript frameworks available to choose from, and Node.js, Next.js, and Express.js are the most popular choice among developers. However, you must consider important factors such as performance, scalability, flexibility, and nature of your web application before making a choice.

Here are the 6 best JavaScript frameworks for 2024 for the back-end.

1. Node.js

Node.js is an open-source server platform that can be used with Windows, Linux, Unix, macOS, and other operating systems. Node.js uses the V8 JavaScript Engine, a back-end runtime environment for JavaScript, to execute JavaScript code outside a web browser.

About thirteen years after the release of the first server-side JavaScript environment, Netscape’s LiveWire Pro Web, Ryan Dahl created the original version of Node.js in 2009. Only Linux and Mac OS X were supported in the initial edition. And to create the OpenJS Foundation, the JS Foundation, and Node.js Foundation combined in 2019, and since then, Node.js has been ranked top for best JavaScript frameworks.

Node.js only natively supports JavaScript, although several languages can be translated into JS. Because of this, Node.js apps may be created in various languages, including Dart, TypeScript, ClojureScript, and CoffeeScript.

Node.js is supported on macOS, Linux, and Microsoft Windows, as well as tier 2 support for SmartOS, IBM AIX, and FreeBSD. Additionally, OpenBSD runs on IBM I (AS/400), and LTS versions are available.

Node.js Usage Statistics:

• Node.js used to dominate as the most popular technology in Stack Overflow annual survey for the last two years; however, it holds the first place in most popular web frameworks and technologies in the 2023 survey.
• The typical response time for the identical page at PayPal decreased by 35%. Pages are served 200ms more quickly when Java is replaced with NodeJS.
• Current version – Node v21.6.0
• GitHub – 102k+ Stars, 27.4k+ Forks, 3338+ Contributors.
• NPM –Node.js recorded 168,860+ weekly downloads on NPM.

Pros of Using Node js:

• As efficiency rises, so will the cost of servers and the personnel required to run them. Additionally, scaling-related performance loss can be avoided. Although most developers prefer running Node on scalable cloud clusters, the task may be completed with a VPS server or an inexpensive dedicated server.
• Can reduce development costs to 58%, and it is growing faster than any other JavaScript framework.
• Organizations that have used Node.js for more than two years have witnessed a 12% decrease in development costs.

Cons of Using Node js:

• Node.js uses an event loop for concurrency and runs on a single thread. This design decision enables it to handle many connections efficiently, but it also implies that long-running blocking processes will halt the entire process and impede the processing of more requests. Performance bottlenecks may result from this, especially in programs that use a lot of CPU power or have a lot of I/O.
• There is no native method for multithreading or parallel processing in Node.js. It is single-threaded and runs on a single process, making it challenging to use multi-core systems to their maximum potential.
• JavaScript, which is used by Node.js and is renowned for its versatility and usability, can be challenging for developers unfamiliar with it. Because JavaScript differs from other widely used programming languages like Java, C++, and Python.

2. Next.js

Next.js is an end-to-end server-side rendering framework based on React. Next.js was created by the Dutch company Vercel (previously known as ZEIT) in 2017. Although both Next.js and Gatsby are based on React, there is one key difference between the two. While Gatsby is a static site generator, Next is an SSR-Server-side renderer.

But remember, Next.js does offer static generators as well. Next.js is built with the principle of “Build once, runs everywhere,” which means that you can make web applications with Next.js, mobile apps, desktop apps, and progressive web apps.

Next.js Usage Statistics:

• Next.js ranks first for the most used back-end JavaScript frameworks on the State of JS report 2022, leaving behind Express and Nuxt.
• 48.6% of JavaScript devs polled are currently using Next.js. But what’s even more impressive is that a whopping 65.2% of devs are interested in giving the next one a try.
• Current version – 13.1.6
• GitHub – 119k+ Stars, 25.4k+ Forks, 3167+ Contributors.
• NPM – Next has clocked close to 6,079,295+ weekly downloads on NPM.

Pros of Using Next.js:

• Server-side rendering – Next.js has SSR (server-side rendering) out of the box to deliver much faster performance as it doesn’t have to wait for the client’s browser to load JavaScript to show content. SSR makes Next.js one of the best JavaScript frameworks for back-end development.
• SEO friendly – Traditional Client side rendered apps have poor SEO performance. Search engine crawlers face difficulties in indexing such pages. However, Next.js, with its server-side rendering capability, delivers an excellent SEO performance. Next.js allows us to create dynamic meta tags in the head section to optimize SEO.
• Automatic code splitting – This feature in Next.js allows us to break down our application code into a series of small bundles, loaded separately as needed, without leading the entire JavaScript code. This helps to deliver blazing-fast optimal performance.
• Pre-fetching – This feature in Next.js allows the lightweight bundles of JavaScript code mentioned above to be lazy-loaded behind the scene.
• Hot-code reloading – Next.js automatically reloads the page when a change is detected.
• Deploy everywhere – With Next.js, you can build small-scale static websites and enterprise-scale applications. Moreover, you can build not only web applications but also mobile apps, desktop apps as well as progressive web applications too.

Cons of Using Next.js:

• Gatsby might be a better option than Next.js for smaller blogs where static build delivers a much more favorable and better performance than Next.js server-side rendering.
• Performance benchmarks of Next.js are, in most cases, inferior to Gatsby and Nuxt.
• Requires back-end server side to provide data.
• Next.js is built specifically to work with React only.

It’s so popular that it is considered one of the best JavaScript frameworks for back-end with Node.js, especially in MEAN or MERN stacks. With almost 48k Stars, it’s the most popular Node.js framework on GitHub.

TJ Holowaychuk built Express in 2010 before being acquired by IBM (StrongLoop) in 2015. Node.js Foundation currently maintains it. The key reason Express is one of the best JavaScript frameworks is its rapid server-side coding. Complex tasks that would take hours to code using pure Node.js can be resolved in a few minutes, thanks to Express. On top of that, Express offers a robust routing mechanism for handling highly dynamic URLs compared to the basic and rudimentary one offered by Node.js.

Express Usage Statistics:

• As per Stack Overflow’s developer survey 2023, Express was ranked 4th most popular web framework overall and by professionals.
• Current version – 4.18.3
• GitHub – 63.4k+ Stars, 13.2k+ Forks, 303+ Contributors.

Gatsby automatically compiles the most appropriate webpack config and handles optimization, prefetching, lazy loading, and fast rendering by default to maximize your website’s performance.
• SEO Friendly – Static content generated by Gatsby is easily readable by Search engine crawlers and offers no hindrance like other JavaScript frameworks.
• Out-of-the-box PWA – Converts your website into a full-fledged Progressive Web App that enhances the user experience.
• Supports Multiple Data sources – Collects data not only by markdown but also various other remote data sources like WordPress, Drupal, Netlify, Contentful, Trello, Stripe, etc.
• High Security – Offers implicit security as it does not require any server, database, or dependencies.
• Plugins – Gatsby’s rich and extensive plugin architecture will offer you a plugin for every task you can accomplish – image optimization, setting up google analytics, creating sitemaps, robot text files, caching, etc.

Cons of Using Gatsby:

• Not suitable for Large-scale Websites – Gatsby is not an ideal solution for content-heavy enterprise-scale websites like e-commerce stores or extensive media websites. Build time will drastically increase as the size of the content grows. This will lead to a significant drop in website performance. Gatsby is a perfect solution for small or medium-scale applications but large enterprise-scale websites.
• Prerequisite Knowledge – Although learning to use Gatsby is fairly easy, a prerequisite knowledge of React and a little GraphQl is necessary.
• Hosting – Hosting with Gatsby is not straightforward, like using a normal website on Site ground, GoDaddy, or HostGator.

Choosing the Right Framework for your Project?

It is important to select the best JavaScript frameworks for front-end, back-end, and testing. It’s crucial to remember that every framework may have distinct benefits and drawbacks, and what works for one project might not for another. It is essential first to comprehend the project’s requirements, including the kind of application you want to create, your preferences for features, and your needs for scalability. After that, think about the framework’s functionality, the level of community support offered, your team’s learning curve, and how simple it is to use.

Testing for scalability is also a crucial factor to consider, especially if you anticipate your project growing over time. Additionally, it’s essential to consider any integrations you may need, such as payment gateways, databases, or APIs, and whether the framework you are considering has the necessary tools and plugins. Lastly, budget is also a factor to consider. Some JavaScript frameworks may be free and open-source, while others may require a license or subscription. It’s important to carefully evaluate your options and weigh the pros and cons of each framework before making a final decision.

It’s worth mentioning that there is no one-size-fits-all answer to this question, and the proper framework for your project will ultimately depend on your specific needs and requirements. It is crucial to thoroughly evaluate your options and seek the advice of experts in the field if necessary.

No matter whatever JavaScript framework you choose, it is recommended to test your JavaScript-developed applications on a real device cloud to test them in real-world environments.
