Chapter 2. Details of the Language

For experienced programmers to pick up a new language quickly, they look for similarities at the core of the new language and other languages they have used. These similarities generally include operators that make programs think, variables that provide memory, and the ability to apply the same operation to various items. Understanding how to use these core pieces of the language is essential if you want to begin programming in JavaScript.

If you have been programming for a long time, you might be tempted to skip over this chapter. Because JavaScript is still a young scripting language with some wrinkles to be ironed out, it is a good idea to understand these instances for backwards compatibility reasons. Taking a little time to make sure the core elements perform as you are expecting will save a lot of programming time in the future.
