Eloquent JavaScript
A Modern Introduction to Programming
by Marijn Haverbeke

Eloquent JavaScript is a book providing an introduction to the JavaScript programming language and programming in general.

A concise and balanced mix of principles and pragmatics. I loved the tutorial-style game-like program development. This book rekindled my earliest joys of programming. Plus, JavaScript!
