# Variables and the Console

You can use the console to play and experiment with JavaScript.

# First, in your JavaScript editor, define some variables.

Variables are like "handles" that we can create to "hold on" to a value that a program will use.

1. We use the word const to declare a variable that is not going to change.

const cats = 3;
const dogs = 4;

2. Click the "console" button at the bottom of the page.

3. Type dogs into the console and see what happens. You should see:

> dogs
4
