What are the best practices for using componentDidUpdate in React?

When using componentDidUpdate, ensure you avoid unnecessary state updates to prevent infinite loops.

Can you give an example of how to use it properly?

Sure! You can check if props have changed and then update the state accordingly, like this:

componentDidUpdate(prevProps) {
  if (this.props.value !== prevProps.value) {
    this.setState({ derivedValue: this.props.value });
  }
}

What should I avoid doing in this lifecycle method?

Avoid making API calls directly in componentDidUpdate unless necessary, as it can lead to performance issues.

Are there any alternatives to using componentDidUpdate?

Yes, you can use the useEffect hook in functional components, which can handle similar logic more cleanly.
