JavaScript Console Intro

These files are intended to be used with the JavaScript Console in Chrome.

The idea is that someone brand-new to programming could have this file open:

JavaScript Intro

And along with the Console, type or copy/paste from that page to begin to understand:

1. Variables
2. Data Types
3. Arrays
4. Booleans and Comparisons
5. if/else Statements
6. for Loops

After that, this second file -- JavaScript Functions, also used in conjunction with the Console -- can help a newbie understand:

1. Creating and calling a function
2. Arguments
3. Returns
4. Scope

The order of examples follows Chapter 19 in Learning Web Design Fourth Edition A Beginner’s Guide to HTML, CSS, JavaScript, and Web Graphics, by Jennifer Niederst Robbins. The examples are my own, although they are aligned with examples given in the chapter.

A third file -- JavaScript Syntax Practice -- is also set up for practice using the console. It covers the following property, methods and functions:

• length
• substring()
• toString()
• parseInt()
• isNaN()
• Math.random()

I chose these because they come up often in early programming exercises, and I thought it might be nice to corral them all in one place for easy reference.
