On: If Not SPAs, What?

[mercer]

I'd say Eloquent Javascript (available for free online, I think) is a good book to read. "You Don't Know JS" is also a good one!

Basically, go for anything that teaches you non-js-specific approaches as well as as a solid understanding of the fundamentals.

Thank you! I'll check both of those out

And Crockford’s JavaScript: The Good Parts. Although and older book, JavaScript fundamentals never change and it describes a lot of those forgotten foundations.
