How to call JavaScript function inside ExtendScript?

[livl17017666]

I am trying to create extension and I need some function from javascript file that I want to use inside extendscript.

That function can not be run inside extendscript, only inside javascript, so how to call JavaScript function inside ExtendScript??

I have javascript file with some functions I would like to use that functions inside extendscript file. Both javascript and extend script are part of extension.

I known for: 
var csInterface = new CSInterface();
csInterface.evalScript..
