What are fetch and promises in JavaScript?

Can you explain what fetch and promises are in JavaScript?

Sure! Fetch is a modern way to make network requests in JavaScript, and promises are used to handle asynchronous operations.

How does fetch work with promises?

When you use fetch, it returns a promise that resolves to the response of the request. You can then use .then() to handle the response.

Can you give me an example of using fetch with promises?

Absolutely! Here's a simple example: fetch('https://api.example.com/data') returns a promise. You can chain .then(response => response.json()) to parse the JSON.

What happens if the fetch request fails?

If the fetch request fails, the promise will be rejected. You can handle errors using .catch() to manage any issues.
