In case someone is clicking this with hopes of learning JavaScript, I mostly agree with the author in that it's better to learn core JavaScript before you delve into any fancy libraries, or even the DOM API (although you probably should have a grasp of HTML & CSS if you intend to do front-end development).
I haven't looked into any of the resources the author has posted, but I've been compiling a list of free web books[1] for myself and friends. I highly recommend checking out either Eloquent JavaScript if you're new to programming, or MDN's Reintroduction to JavaScript or the Modern JavaScript Tutorial if you already have programming experience.
