AbortController is a modern API that allows you to abort fetch requests, while XHR (XMLHttpRequest) is an older method for making HTTP requests.
Can you explain how to use AbortController?
Sure! You create an instance of AbortController, then pass its signal to the fetch request. You can call abort() to cancel the request.
Is XHR still relevant today?
While XHR is still supported, it's generally recommended to use the Fetch API with AbortController for better functionality and ease of use.
