Lua is a dynamically typed programming language created in Brazil in the early 1990s.

It is designed to be embedded inside larger applications, giving developers a flexible way to add scripting, configuration, or automation without heavy overhead. Because of its compact design and fast interpreter, Lua is widely used in games, networking tools, IOT devices, and applications that need a customizable runtime.

The games it’s listed in include:

Angry Birds – Uses Lua for physics, logic, and game flow.
World of Warcraft – Uses Lua for UI customization and add‑ons.
Factorio – Listed among Lua‑scripted games.
Grim Fandango – Early example showing Lua’s power in game development.

While the language is easily read, it is best for embedded use. All you get is a command line interface. And while there are GUI widgets it could use, this is nowhere near an integrated GUI development programming language.
