Even though the asynchronous requirement is good for developers using the promise API, it really screwed over implementors.&lt;p&gt;The setImmediate polyfills attempt a bunch of ugly fallbacks, including (depending on which one you use): yield&amp;#x2F;generators, MutationObserver, postMessage&amp;#x2F;MessageChannel, onreadystatechange, and finally setTimeout (the slowest).&lt;p&gt;IMO the browser vendors should just give in and add setImmediate – if ever there was a need for it, this is it. But maybe they consider ES6 features a good enough substitute, I don&amp;#x27;t know.</text><parent_chain></parent_chain></comment><story><title>JavaScript Promises in Wicked Detail</title><url>http://mattgreer.org/articles/promises-in-wicked-detail/</url></story>

And from the author&amp;#x27;s perspective, whether they are writing it to take advantage of the opportunity for increased page-views.</text><parent_chain></parent_chain></comment><story><title>JavaScript Promises in Wicked Detail</title><url>http://mattgreer.org/articles/promises-in-wicked-detail/</url></story>
