A series of posts on using functional programming concepts in everyday ActionScript and JavaScript code. Uses underscore.js and underscore.as. This series is very code-heavy, but covers a lot of very practical techniques you can use to improve your code, from repetitive list filtering to high-level architecture.

• Introducing underscore.as
• Anonymous Functions in AS3
• Understanding Closures and Context
• Closures in List Transformation
• Function Transformation
