Objects in JavaScript
JavaScript is like PHP, ActionScript, or Python in that it can be coded as a top-down, procedural language (run one statement at a time, working your way from top to bottom) or it can be coded using the Object-Oriented Programming (OOP) paradigm. This makes JavaScript one way for a teacher to introduce Object-Oriented Programming in small chunks.

- navigator
