NuGet GalleryLua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics.
Lua is dynamically typed, runs by interpreting bytecode for a register-based virtual machine, and has automatic memory management with incremental garbage collection, making it ideal for configuration, scripting, and rapid prototyping.
