JavaScript Code, Secret of JavaScript Ninja

JavaScript developers commonly rely on collections of reusable JavaScript code--written by themselves or by someone else at their company. Alternatively, they rely on code from a third party. But in all these cases they need to know how to either construct a cross-browser library from scratch or be adept at using and maintaining their library of choice.

This Book is intended to take an intermediate JavaScript developer and give him the knowledge he needs to create a cross-browser JavaScript library, from the ground, up. Due to the challenging issues that are continually encountered when developing cross-browser JavaScript applications JavaScript libraries have become a necessity of modern JavaScript development. All JavaScript developers have a collection of reusable code - either written by themselves, someone at the company that they work at, or by a third party. Thus, it becomes increasingly important that a JavaScript developer understand how to, either, construct a library from scratch or understand how their library of choice works.
