Variables and Types
A variable is a named piece of data. You can use a variable to store a value within your program, and refer to it later by the variable name.
Variables are defined using
myFirstVariable = "I made a variable!"
Once you have assigned a value to a variable, you can then refer back to it:
There are three main types of variable:
- Strings (a collection of symbols inside speech marks)
- Booleans (true or false)
Numbers (numeric values)
aString = "I'm a string!" aBoolean = true aNumber = 42
Define three variables,
myNumber, and set them to "I'm programming!", "true", and "5".
