The Little JavaScript Book
The Little JavaScript Book
All you wanted to know about JavaScript but never dared to ask.
About the Book
Why another book on JavaScript? As much as I love masterpieces like "You don't know JS" and "Eloquent JavaScript" I feel there is the need for a book which takes the reader by hand, challenging enough, yet concise.
In this book you'll learn the hard parts of JavaScript without the gimmicky packaging that comes with some tutorials, and most important without arid academic lucubration. It aims to be a concise reference, while never peeking too much into the JavaScript spec.
Enjoy the reading!
