What are the best programming language tutorials?

[CamelCaseName]

Regardless of language, what is the best (clearly written, examples smoothly build on each other, easy to understand) guide you have come across?

Background: I am working my way through Hartl's Rails tutorial because of it's high recommendations and want to continue my self-education.

If u need the very best, then go checkout https://vuejs.org. Its not a language, but a framework. It just can't get any better than that. Every tutorial must be written by taking an inspiration from VueJS docs.

I'd have to go with the drRacket one on this: http://docs.racket-lang.org/quick/index.html

I really like it if I can mess around with visual stuff quite soon when learning a new language.
