Harmes, Diaz: Pro JavaScript Design Patterns

 homepage of the book

Chapters from a JOBAD point of view:

1. Expressive JavaScript: the basics for high-level programming in JS, a must-read
2. Interfaces: something you know from object-oriented language and that will be useful for the design of a library. They describe how to do it in JS.
3. Encapsulation and Information Hiding: another basic object-oriented concept
4. Inheritance: same. There are several ways of doing it in JS.
5. The Singleton Pattern: may be needed for certain global JOBAD objects, e.g. the document-wide event handler
6. Chaining: is provided by jQuery, AFAIK, but this chapter is helpful for understanding it. Note that the book is quite generic; it doesn't mention jQuery explicitly.
7. The Factory Pattern: There is an Ajax-related example of a factory for XmlHttpRequest objects, which may be useful.
8. The Bridge Pattern: Not sure whether we need this
9. The Composite pattern: Not sure either
10. The Facade Pattern: May be useful when integrating functionality from existing libraries, e.g. JavaScript standard functionality like DOM, or jQuery, and providing convenience functions.
11. The Adapter Pattern: They have sample code related to library integration
12. The Decorator Pattern: Not sure about this
13. The Flyweight Pattern: Not sure either
14. The Proxy Pattern: Not sure either
15. The Observer Pattern: Not sure either
16. The Command Pattern: seems quite useful to me for implementing the commands behind menu items, buttons, and any other GUI elements in a uniform way.
17. The Chain of Responsibility Pattern: Not sure about this
