What are the differences between useEffect hook and class components in React?

The useEffect hook allows you to perform side effects in functional components, while class components use lifecycle methods.

Can you give me an example of how useEffect works?

Sure! Here's a simple example: useEffect(() => { document.title = 'Hello World'; }, []); This sets the document title when the component mounts.

What are the advantages of using hooks over class components?

Hooks like useEffect allow for cleaner and more reusable code, and they help avoid issues with this binding in class components.

Are there any downsides to using hooks?

One downside is that hooks can lead to complex component logic if not managed properly, especially with multiple effects.
