This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The aborted read-only property returns a Boolean that indicates whether the DOM request(s) the signal is communicating with is/are aborted (true) or not (false).
var isAborted = abortSignal.aborted;
A Boolean
In the following snippet, we create a new AbortController object, and get its AbortSignal (available in the signal property). Later on we check whether or not it the signal has been aborted using the aborted property, and send an appropriate log to the console.
var controller = new AbortController();
var signal = controller.signal;
// ...
signal.aborted ? console.log('Request has been aborted') : console.log('Request not aborted');
