Its initial state is empty 44 // string for title, instructions, img and an empty array for ingredients45 // it has onSubmit event, onClick event, and several onChange events with associated function calls46 // onSubmit event triggers a onSave call (passed as prop from App component) and state is updated.47 // onClick event reset the form.48 // onChange event set the state to the values entered by the user as new recipe.49 // onSave passed from App component through the props is linked to this.handleSave in the App component50 // By submitting the form, onSave function call allows App component, parent of Form, to acquire the new51 // recipe values and add it to its state.recipes array. The event happens in Form component, but it 52 // is being implemented in App component. Remember data travels down the tree only, not upstream or between53 // siblings. In order for the new recipe to be listed, the new recipe values must pass to List54 // component. It cannot happen directly. So, Form "communicate" the new recipe values to App through onSave call55 // then App component passes its new state (with the new recipe) downstream as prop to List component56 // ** HOW DO YOU PASS
