What are the differences between popular API libraries?

Can you explain the differences between Axios and Fetch for API calls?

Sure! Axios is a promise-based HTTP client that works in both the browser and Node.js, while Fetch is a built-in browser API. Axios automatically transforms JSON data, whereas Fetch requires you to call .json() on the response.

What about error handling? How do they differ?

Axios has built-in error handling and will reject the promise for HTTP errors, while Fetch only rejects on network errors. You need to check the response status manually with Fetch.

Which one is better for large applications?

For large applications, Axios is often preferred due to its features like interceptors, automatic JSON transformation, and better error handling.

Are there any performance differences between them?

In general, both perform similarly for most use cases, but Axios may have a slight overhead due to its additional features. Fetch is more lightweight.
