What are some debugging tips for React 18?

Here are some tips: 1. Use React DevTools for component inspection. 2. Check for common hooks issues. 3. Utilize error boundaries.

How can I effectively use React DevTools?

You can inspect the component tree, view props and state, and track re-renders to identify performance issues.

What are error boundaries and how do I implement them?

Error boundaries are React components that catch JavaScript errors in their child component tree. You can implement them by creating a class component with a static getDerivedStateFromError method.

Can you give an example of using error boundaries?

Sure! Here's a simple example:

class ErrorBoundary extends React.Component {
  static getDerivedStateFromError(error) {
    return { hasError: true };
  }

  componentDidCatch(error, info) {
    console.error('Error caught:', error);
  }

  render() {
    if (this.state.hasError) {
      return <h1>Something went wrong.</h1>;
    }
    return this.props.children;
  }
}
