JavaScript Essentials: Using The Console

In this JavaScript Essentials tutorial, you’ll learn how to get started using the console and write your first JavaScript statements.

In order to get started writing JavaScript, you’re going to need an environment in which to write JavaScript source code. Luckily you can write it directly in the developer tools of any browser you might have access too. Also, if you have a Mac, you can use the RunJS program to write JavaScript in an interactive environment.

In the tutorial, you’ll learn how to use the JavaScript console and write your first JavaScript statements including the ubiquitous ‘Hello World’ program and also how to do some arithmetic with JavaScript.

At the end of the lesson, you should have a pretty good idea of how to print messages to the console with JavaScript.
