Javascript library resouces

[waynecd]

Hi,

Where can I find resouces that can show me how to code a Javascript library for efs?

I understand that a library (...efsLib) is just a set of functions without a main().

Things like:
-you can't draw on a chart [i.e., drawLineRelative()] if the code is in the ...efsLib
-an efsLib should only return one value, etc
-efsLib should not have global variables

Any tips and resources I can study would be appreciated.

Thanks

Wayne
