AbortSignal.abort()

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();
controller.abort();
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 organised 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

Syntax
