In this final chapter, you learned about some common JavaScript coding patterns and learned how to make your programs cleaner, faster, and better at working with other programs and libraries. Then you saw a discussion and sample implementations of some of the design patterns from the Book of Four. You can see how JavaScript is a fully-featured dynamic object-oriented programming language and that implementing classical patterns in a dynamic language is pretty easy. The patterns are, in general, a large topic and you can join the author of this book in a further discussion of the JavaScript patterns at the web site JSPatterns.com.

You now have sufficient knowledge to be able to create scalable and reusable high-quality JavaScript applications and libraries using the concepts of Object-Oriented Programming. Bon voyage!
