setImmediate via MessageChannel

This article will briefly describe another method of implementing a “zero” delay setTimeout (callback, 0).
Anyone who is interested - under the cat.

Briefly about the main thing

Standard setTimeout makes the minimum delay of a few milliseconds, in IE 10 even invented setImmediate which allows you to set a "zero" delay. How it works is well written here ie.microsoft.com/testdrive/Performance/setImmediateSorting/Default.html

Sample code that works in Chrome, Safari, Opera
function setZeroTimeout(callback) {
var channel = new MessageChannel();
channel.port1.onmessage = callback;
channel.port2.postMessage('');
}


Virtues
