Eloquent JavaScript is a guide to JavaScript that focuses on good programming techniques rather than offering a mish-mash of cut-and-paste effects. The author teaches you how to leverage JavaScript's grace and precision to write real browser-based applications. The book begins with the fundamentals of programming-variables, control structures, functions, and data structures-then moves on to more complex topics, like object-oriented programming, regular expressions, and browser events. With clear examples and a focus on elegance, Eloquent JavaScript will have you fluent in the language of the web in no time.
