* 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" :) | |
* | |
* 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 | |
* console.assert(foo === bar, 'Y U NO EQUAL?', true); // Will stop execution and open dev tools | |
