The aborted read-only property returns a value that indicates whether the DOM requests the signal is communicating with are aborted (true) or not (false).

true (aborted) or false

In the following snippet, we create a new AbortController object, and get its AbortSignal (available using the signal property). Later on, using the aborted property, we check whether or not the signal has been aborted, and send an appropriate log to the console.

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

// …

if (signal.aborted) {
  console.log("Request has been aborted");
} else {
  console.log("Request not aborted");
}
