Learn how to store and work with data in Lua! In this episode, we cover the local keyword, the four core data types — string, number, boolean, and nil — and how to inspect any value with type(). Every keystroke is shown on screen with 3-second pauses so you can follow along at your own pace. What You'll Learn: - Declaring variables with local - The string, number, boolean, and nil types - Checking a value's type with type() - Why nil means "nothing" in Lua - Printing variables alongside strings using .. - How Lua handles uninitialized variables (they're nil!)
