Tried to use classes? Well, there’s part of your problem. JavaScript wasn’t really made for it but class was forced into it. It was a pointless, useless addition to the language. Try going a different path, a different way of OOP in JS, or try functional programming.

Another problem you might be having is that you’re diving too deep, too fast into JS before you understand the basics of it. JavaScript is a very different language from C#, C anything, and Python.

Also, you don’t need all of those tools. In fact I’d advise that you don’t use any tools, except jQuery, if you’re relatively new to JS. This goes for any language. Make small things, small components, and build up from there. Essentially, approach it like it was your first time.
