What is the key difference between the useEffect hook and the traditional lifecycle methods in class components?
- Lifecycle methods are only available in functional components.
- useEffect can only be used in class components.
- useEffect cannot be used for side effects.
- useEffect is synchronous, while lifecycle methods can be asynchronous.
The key difference between the useEffect hook and traditional lifecycle methods is that useEffect is synchronous, while traditional lifecycle methods in class components can be asynchronous. This means that useEffect allows you to perform side effects after rendering in a way that won't block the rendering process, making it suitable for tasks like data fetching and DOM manipulation. Traditional lifecycle methods in class components can block rendering, leading to performance issues.
