What are the performance differences between AJAX and Fetch in JavaScript?

AJAX and Fetch both allow you to make network requests, but Fetch is generally more modern and efficient. Fetch uses Promises, which can lead to cleaner code and better error handling.

Can you explain how error handling differs between the two?

Sure! With AJAX, you typically use the onerror event to handle errors, while Fetch uses the .catch() method with Promises, making it easier to manage asynchronous errors.

Which one should I use for new projects?

For new projects, it's recommended to use Fetch due to its simplicity and better support for modern JavaScript features. However, if you need to support older browsers, AJAX might still be necessary.

Are there any specific performance benchmarks comparing them?

Yes, benchmarks often show that Fetch can be faster due to its streamlined API and better handling of concurrent requests. However, the actual performance can vary based on the use case.
