What are the best practices for using AJAX and Fetch in JavaScript?

When using AJAX, ensure you handle errors gracefully and use callbacks effectively. For Fetch, prefer using async/await for cleaner code.

Can you explain the differences between AJAX and Fetch?

AJAX is a technique that allows asynchronous web requests, while Fetch is a modern API that simplifies making those requests with promises.

Which one should I use for a new project?

For new projects, it's recommended to use Fetch due to its simplicity and better support for promises, making it easier to work with.

Are there any performance differences between them?

Fetch generally has better performance due to its streamlined API and support for streaming responses, but AJAX can be more compatible with older browsers.
