a console.assert which actually stop the execution

dieassert.js

/**
 * A console.assert which actually stop the exectution.
 * default console.assert() is a plain display, such as console.log() or console.error();
 * It doesnt stop the execution like assert() is meant to do. This is a little code to 
 * "workaround this limitation" :) thanks @jensarp
 *
 * Usage:
 * console.assert(foo === bar); // Will throw if not equal
 * console.assert(foo === bar, 'Dude, foo does not equal bar'); // Will throw with custom error message
 *
 * To trigger js debugger on failed assert, do 
 * console.assert.useDebugger = true;
*/
console.assert	= function(cond, text){
	if( cond )	return;
	if( console.assert.useDebugger )	debugger;
	throw new Error(text || "Assertion failed!");
};

Ok, now it's time to use it in real life and see if it proves useful :)

This pauses within the stack of the custom 'assert' function, further search I have found that you can pause on console.assert by enabling it during dev in Chrome Devleoper Tools, see http://stackoverflow.com/questions/12163266/break-into-chrome-debugger-when-console-assert-fails
