Lua is a powerful, efficient, lightweight, embeddable scripting language. It supports several programming styles: procedural, object-oriented, functional, data-driven, and data description. Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, runs by interpreting bytecode on a register-based virtual machine, and has automatic memory management with incremental garbage collection, making it ideal for configuration, scripting, and rapid prototyping.
