|explains= Lua
|description=Lua is used to give template authors more functionality than available through [[Parser functions]]. The debate to use [[JavaScript]] or [[Lua]] was settled in 2012. Lua can be used to analyze data, calculate expressions, and format results using functions stored in so-called 'modules' in the wiki.

Lua is a programming language that is now available, via the [https://www.mediawiki.org/wiki/Extension:Scribunto Scribunto MediaWiki extension], on the English Wikipedia (and on this wiki). Lua code can now be embedded into wiki templates by employing the "<nowiki>{{#invoke:}}</nowiki>" functionality of the Scribunto MediaWiki extension.
