How can you implement fetch cancellation in asynchronous JavaScript operations?
Discuss how to cancel fetch requests in JavaScript to prevent executing unnecessary network calls once they are no longer needed.
Answer
You can implement fetch cancellation using the AbortController API:
- Create an instance of AbortController.
- Pass the signal from the controller to the fetch request.
- If needed, call controller.abort() to cancel the request.
- Handle the abort event in a catch block to manage the cancellation gracefully.
