Yet how many of today's programmers can write pure native Javascript without the aid of a framework? How many can perform AJAX requests without a framework? And most importantly, how many can craft fully cross-browser compatible code without a framework? Dynamic scripting allows your JS to be changed based on the server side or client side situation (or both); different scenarios call for different measures, different variables, and sometimes even completely different code altogether. read more
