Make a dynamically injected function always execute, without the delay of callbacks or the evil of `eval`. Amazingly simple solution that works like a charm. I needed this because I wanted to make dynamically precompiled templates instantly available (in PROD mode they are compiled into a JS file, and injected if a module on the page requires it…

noCallbackInstantExecute.js

/*
using jQuery AJAX as an example, though we do not leverage jQuery in our Production app.
This technique can be used anywhere with injected data/functionality
*/
$.ajax({
	url: theTemplate.filePath,
	success: function(data) {
		/*
		Take the raw data of the file, insert it into a new function, and execute it.
		Bypasses need for callbacks, instantly executes it without delay, and does it without using `eval`.
		Awwwww yeah, suck it eval and callback, you mouthbreathing losers.
		*/
		var thePayload = new Function(data);
		thePayload();
	},
	async: false
});
