YOUR LUA LEARNING PATH

A little more Lua.
A little more confidence.

One idea at a time, with examples you can follow and checkpoints to see what’s clicking. New here? Begin with chapter one. Know a little already? Jump right in.

Before you start

Start with values and truth, then scope and functions. Lua-specific rules such as one-based sequence indexes are introduced in the lessons.

Review a foundation whenever you need it: First Python program · Decisions and loops · Small functions
