Understanding useEffect

The useEffect hook in React performs side effects in functional components. It can resemble the combination of componentDidMount, componentDidUpdate, and componentWillUnmount lifecycle methods in class components. The useEffect hook takes two parameters: a function that contains the side-effect logic and an optional array of dependencies.

Key Points:

Initialization and Clean-Up: Initialize the jsonEditor instance within the useEffect and clean it up in the returned function.

Dependencies: An empty dependency array ([]) ensures that the useEffect runs only once when the component mounts and once when it unmounts. If specific dependencies are provided, the cleanup will run whenever those dependencies change and when the component unmounts.
