Lua Quick Start Guide

Creating variables

To create a variable, you need to do two things:

• Declare the variable
• Assign a value (data) to the variable

As an example, let's make a variable, foo, and assign it the value bar. The code to do this would be:

foo = "bar"

That single line of code declares a variable and assigns a string value to the variable. If you break it into several parts, the actual line of code consists of the following pieces:

Why are there quote marks around bar? What is a string value? These questions will be answered in the coming two sections, Basic types and String types.
