jQuery Forum

Hi, sorry I know this is not a regular question for this forum. I thought though since most of the people on here use javascript/jQuery you might know of some really good resources for understanding Javascript itself. I've got a few books, but they tend to be more of a developers crash course of what they consider the basics. In that they always seem like they're not talking about the foundation or core components that comprise javascript. I was wondering if anyone knows of some really good, indepth books on javascript. Even a book on the historical development from Mocha/livescript to javascript today. I'm getting to the point where it feels awkward using functions and scripts, but not understanding how they actually work. Or more to the point I'm curious as to what the main building blocks of javascript are.

Thought I'd throw it out there. I'm trying to stretch out a bit more to the coding communities, so even if you know of some more dedicated jS communities I could ask, that'd be great too.

Thanks for reading.
