LuaJIT

Lua is a dynamically-typed scripting language offering object-oriented capabilities, designed for extending applications.

Just-in-time compilation (JIT) is a method to dynamically compile code and allow an application to run faster.
LuaJIT is a JIT system for Lua developers, allowing them to create faster running Lua-based apps.
