Overview of this book

The book requires no prior knowledge of JavaScript and works from the ground up to give you a thorough grounding in this powerful language. If you do already know some JavaScript, you will find plenty of eye-openers as you discover just what the language can do. This book takes a do-it-yourself approach when it comes to writing code, because the best way to really learn a programming language is by writing code. You are encouraged to type code into Firebug's console, see how it works and then tweak it and play around with it. There are practice questions at the end of each chapter to help review what you have learned.

Chapter 8. Coding and Design Patterns

Now that you know about the object-oriented features of JavaScript, such as prototypes and inheritance, and you have seen some practical examples of using the browser objects, let's move forward, or rather, move a level up. Let us have a look at some common patterns of JavaScript utilization. First, let's define what a pattern is. In short, a pattern is a good solution to a common problem.

Sometimes when you are facing a new programming problem, you might recognize right away that you've previously solved another, suspiciously similar problem. In such cases, it is worth isolating this class of problems and searching for a common solution. A pattern is a proven and reusable solution (or an approach to a solution) to a class of problems. Sometimes a pattern is nothing more than an idea or a name, but sometimes just using a name helps you think more clearly about a problem. Also, when working with other developers in a team, it's much easier to communicate...
