Chapter 1. Core Concepts

A program is a set of written instructions to be executed (i.e., carried out) by a computer or a software application. The written, human-readable text of a program is called source code, or just code. The person who creates a program is called a programmer, a coder, or a developer. Every program is written in a particular programming language, just as every book is written in a particular language (English, Russian, Japanese, etc.). Programming languages dictate the syntax and grammar that programmers must use to form the instructions in a given program. This book provides from-the-ground-up coverage of the syntax, grammar, and usage of one specific programming language, ActionScript 3.0. Get ready for a good time.
