Question

How would I become a master of JavaScript if I always used frameworks and did nothing by myself?

Answer 1

Javascript, browsers and APIs like the DOM have some bad and tedious qualities. Libraries have been converging on some much better APIs and often relieve you of the need to do things like browser sniffing and so on.

You'll still be using Javascript.

It can also be important to understand what's going on beneath and why certain aspects of libraries are helping you out so much. You never know when you won't have the opportunity to use a library too, so it's important to understand how to do things like interact with the DOM and make cross-browser compatible AJAX requests without a library.
