I see your point... I had discovered recently the lack of JavaScript knowledge. And since I mostly doing web development I realized that I am missing out a lot.
Unfortunately the object oriented approach JavaScript using is different from other object oriented languages I know (C++, C#, Java) So I am trying to get up to speed with JavaScript and making up my own problems/tasks. Like I am learning how 'this' works with JavaScript... So the code I wrote is not promoted by another library :) It's promoted by my background in C++ and C# mostly :) So I chose JQuery as a library to use but before I can freely start using it I want to understand how things work. Cause as of right now if you tell me to write JQuery from scratch I will not be ably even to start :) And even having full source available does not help much since I often do not understand what is going on Thanks George.
