Lua is an easy to learn but powerful scripting language.
MediaWiki supports Modules written in Lua (by the extension Scribunto, bundled with 1.34+) which can simplify writing templates a lot. Especially in cases where a lot of calculations must be done efficiently or when loops are inevitable, Lua is the better choice (if not the only one).
Notes
in mw: Extension:Scribunto#Configuration there are some parameters to limit the impact/load of Lua scripts may have
- memoryLimit - Specify the memory limit in bytes.
- cpuLimit - Specify the CPU time limit in seconds.
- profilerPeriod - Specify the time between polls in sections for the Lua profiler.
- allowEnvFuncs - Set true to allow use of setfenv and getfenv in modules.
There is also an article about a PHP sandbox for Lua (currently not compatible with PHP8)
