Specification

https://github.com/whatwg/dom/pull/1032

Summary

Returns a new AbortSignal object that is automatically aborted after a given number of milliseconds. This method can be used by developers to easily implement timeouts for signal-accepting async APIs, e.g. fetch().

Blink component

Blink>DOM

Motivation

The main motivating use case for this is helping web developers easily time out async operations, such as fetch(). For example, now you can write: fetch(url, { signal: AbortSignal.timeout(10_000) });
