Let's say the user clicks a link while we are still loading some data. Then we can use AbortController, a controller object that allows us to abort one or more web requests, to tell the browser to cancel and ignore the request.

const { signal } = new AbortController();
  
// Pass the same signal to multiple promises
fetch('url-one', { signal });
fetch('url-two', { signal });
  
// Cancel all requests
controller.abort();
