Your First Variable

Typing the same number over and over is boring — and if you want to change it, you have to change every line. Programmers store numbers in a box with a name. That box is called a variable.

let steps = 80

1. 1Make a variable

   Create a box named steps and put 80 inside it.

   let steps = 80

2. 2Add your animal

   Create a tiger.

3. 3Use the variable

   Move the tiger using steps instead of a number.

4. 4Change one line

   Change 80 to 200 on the first line and press Run. Everything below updates automatically.
