AbortSignal: abort() static method

The static AbortSignal.abort() method returns an AbortSignal that is already set as aborted (and which does not trigger an abort event).

This is shorthand for the following code:

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

This could, for example, be passed to a fetch method in order to run its abort logic (i.e. it may be that code is organized such that the abort logic should be run even if the intended fetch operation has not been started).

Note: The method is similar in purpose to Promise.reject.





The reason why the operation was aborted, which can be any JavaScript value. If not specified, the reason is set to "AbortError" DOMException.

Return value

An AbortSignal instance with the AbortSignal.aborted property set to true, and AbortSignal.reason set to the specified or default reason value.
