Is the Fetch API an ECMAscript feature?

Question

I\'ve looked through the MDN resources here as well as here, as well as the WhatWg Fetch Spec, and for all that I can\'t figure out if the Fetch API is part

Answer 1

No. Most of the BOM (BrowserObjectModel) which is exposed by window object are part of WHATWG and W3C. example: navigator, ajax, fetch, etc.,

The spec for Fetch is present https://fetch.spec.whatwg.org/

If you want references in w3c look for Service Worker and search for the term http fetch

ECMASCript features will be listed in ECMA spec https://www.ecma-international.org/ecma-262/7.0/index.html

Note: BOM itself is an informal term
