tailieunhanh - Pro JavaScript™ Techniques

The evolution of JavaScript has been gradual but persistent. Over the course of the past decade, the perception of JavaScript has evolved from a simple toy language into a respected programming language used by corporations and developers across the globe to make incredible applications. The modern JavaScript programming language—as it has always been—is solid, robust, and incredibly powerful. Much of what I’ll be discussing in this book will show what makes modern JavaScript applications so different from what they used to be. Many of the ideas presented in this chapter aren’t new by any stretch, but their acceptance by thousands of intelligent programmers has helped to refine. | JavaScript Techniques Real-world JavaScript techniques for the modern professional web developer John Resig Aprcss Pro JavaScript Techniques John Resig Apress Pro JavaScript Techniques Copyright 2006 by John Resig All rights reserved.
