What are promises in the Fetch API?

Can you explain what promises are in the Fetch API?

Sure! Promises in the Fetch API represent the eventual completion (or failure) of an asynchronous operation and its resulting value.

How do I use promises with Fetch to handle responses?

You can use the .then() method to handle the response once the promise is resolved. For example, fetch(url).then(response => response.json()).

What happens if the fetch request fails?

If the fetch request fails, the promise is rejected, and you can handle the error using the .catch() method.

Can you give me an example of error handling with Fetch?

Certainly! You can do something like this: fetch(url).then(response => { if (!response.ok) throw new Error('Network response was not ok'); return response.json(); }).catch(error => console.error('Fetch error:', error));.
