3. Functions

What is a Function?

Calling a Function Parameters

Pre-defined Functions

parseInt() parseFloat() isNaN() isFinite() Encode/Decode URIs eval() A Bonus—the alert() Function

Scope of Variables Functions are Data

Anonymous Functions Callback Functions Callback Examples Self-invoking Functions Inner (Private) Functions Functions that Return Functions Function, Rewrite Thyself!

Closures

Scope Chain Lexical Scope Breaking the Chain with a Closure

Closure #1 Closure #2 A Definition and Closure #3 Closures in a Loop

Getter/Setter Iterator
