the size of the javascript library relatively [not to the power of it , but to the size of my entire app , and my environment which considers the size of app strongly] large. And I guess that there can be unused lines of codes. For example,In my case, I dont use any of the visual tables... we can reduce the size if we can remove relevant code...What do you suggest to minimize the size of JS lib?

[as the code is cryptic, going through the code would not be that much easy. I suggest to have a custom build js lib]
