# Variables I

# What are they?

For variables I will use the analogy of a nametag.

Nametags are warn by people and each person can hold one piece of data. In these first examples we will use Strings.

TIP

Strings are any characters surrounded by quotation marks("")

Example

"This is a string!" // String
"555555" // String
"There are numbers here but this is still a string 2#%@#$@$!" // String
"true" // String
"variable" // String

# Scenario - Creating a variable to equal the string "Pizza"

When we create variables we actually create a nametag for data that's typically much longer. We do this because we can:

  • Make things more human readable
  • Allows us to reuse the data without remembering what was inside of it
Pizza girl holding pizza
var food = "Pizza"
