Strings

Part of the Fundamentals section of Coddy's Lua journey — lesson 6 of 90.

A string is a sequence of characters used to represent text in your programs.

In Lua, you can create strings by wrapping text in either single quotes or double quotes. Both work exactly the same way:

playerName = "Coddy"
gameTitle = 'Adventure Quest'
