I'm a professional software developer. I've been programming in a lot of different languages over the course of more than two decades now. Picking up a new programming language is very easy for me.
However, I have no knowledge or experience whatsoever developing modern AJAXy web applications. What I need is a book that gives me a good overview over the technologies involved, most notably on the client-side, code samples that I can play around with and pointers to more in-depth stuff.
What I don't need is a chapter on how loops work or how to traverse a tree.
Any good ones?
