How to handle Compatibility issues with certain versions of Node.js or Chrome?

Node.js is a JavaScript extension used for server-side programming. Error management is a necessary stage in the creation of applications. Working with both synchronous and asynchronous functions at once is possible for Node.js developers. Asynchronous functions must be handled carefully since, unlike synchronous functions, their behavior can change.

While try-catch blocks are helpful for synchronous operations, callbacks, promises, and async-await can be used to handle asynchronous functions. If an asynchronous function throws an error in a synchronous try/catch block, no error is thrown, meaning that try-catch is synchronous.

There are several ways to manage errors in Node.js applications:

  • Use Try-catch block - To handle errors that a piece of code throws, utilize the try-catch block.
  • Use Callback - In Node.js, callbacks are frequently utilized because they avoid blocking and let another code run. The program does not wait for the file reading to be finished before printing "Program Ended" and proceeding with the file reading. The file's content is outputted unless an error occurs, such as a file not existing in the system, in which case the error is shown following "Program Ended."
  • Use promise callbacks and promises - A development above Node.js callbacks is promised. The value returned when defining the callback is referred to as a "promise." The return value is the main distinction between a promise and a callback. The promise module must be imported into the application and installed before it is used. The .then clause handles the output of the promise. The program ends if a promise is denied and there is no error handler.
  • Use async-await - A specific syntax called async-await makes it easier to understand and interact with promises. When we use async/await, await takes the place of .then, which manages the function's waiting. The .catch clause handles any errors that arise. For error management, async-await can be encapsulated in a try-catch block. If there is no error handler, the program crashes because of an uncaught error.
