JavaScript modifications to feature in Blend4webs' iframe

Hi, I am hoping to introduce further JavaScript mortification to a feature contained within Blend4web's frame coded feature. I just wish to ask if anyone could recommend any decent (newbie) JavaScript forums which would be knowledgeable about applying modifications to this iframe feature? Thanks
