The Lua scripting language (not "LUA" the acronym, "Lua" as in a proper noun) is a scripting language used by Touch Lua. It is used in many applications and games, most notably Roblox due to its extensive power for making games.

As of late 2014 Wikia itself uses the Lua scripting language as a templating language to set up Infoboxes and other components of a page, in an attempt to improve the load speed of pages.
