Summary

Objects are the fundamental nature of everything in JavaScript. The examples in this chapter will start you down the road to deeply understanding how JavaScript works and how to write code that takes full advantages of its capabilities. By using objects to contain related code elements, you take control of your code as it grows and prevent scoping conflicts. By creating objects from which you can create instances, you have a powerful mechanism for managing large data sets.

DOM scripting enables you to manipulate the user interface and takes your Web page from a fixed layout to a fluid canvas that you can modify at will.
