How can I use advanced features of the Fetch API?

The Fetch API provides advanced features like streaming, aborting requests, and handling CORS. What specific feature are you interested in?

Can you explain how to abort a fetch request?

Sure! You can use the AbortController to abort a fetch request. Here's a quick example:

const controller = new AbortController();
const signal = controller.signal;

fetch('https://api.example.com/data', { signal })
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(err => {
    if (err.name === 'AbortError') {
      console.log('Fetch aborted');
    }
  });

// To abort the request:
controller.abort();

What about handling CORS issues?

To handle CORS issues, ensure the server includes the appropriate headers like Access-Control-Allow-Origin. You can also use a proxy server if needed.
