Lua is available as a templating language on FANDOM, helping to provide users with the ability to create more maintainable templates, and to improve the performance of some of our slowest pages.
Lua is a different coding experience to basic wikitext templates, resembling a more 'traditional' programming syntax. It offers two key advantages: first and foremost is that logical functionality – 'if', 'else', and 'while' statements along with arrays and variable definition, for instance - is built in to the Lua language, making the implementation of basic logic much easier in Lua than via MediaWiki's other methods. Secondly, because Lua is streamlined for logical operations, it is much more technically efficient.
Enabling and support
Lua is enabled by default on all wikis. When enabled, the general standard Lua libraries along with the specialized Scribunto libraries are also available. Additionally, InfoboxBuilder will be automatically bundled in the installation.
Lua modules can also be loaded from the FANDOM Open Source Library using require("Dev:ModuleName"), as opposed to require("Module:ModuleName")[1]. These so-called "global modules" are described in more detail here.
