Actionscript Salon #1: Functions & Prototypes

Functions are a basic piece of programming and a must for the beginning Actionscripter. They reduce the quantity of your code by making blocks of it re-usable, and increase quality by making it more readbable and more flexible.

In Actionscript 1 - before true Class files became available in AS2 - 'prototype' was the essential keyword for building classes.

This salon has information still useful for the beginner trying to get his/her head around the introductory concept of functions, and possibly useful for more advanced developers who find themselves inadvertently thrust back into the AS1 world.

Relevance/availability: prototypes are an Actionscript 1 concept. If you are using Actionscript 2 or 3, this Salon will be of little value. Functions have changed structure slightly since this Salon was first given, but the information is still relevant.
