|
|
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
|
|
for a register-based virtual machine, and has automatic memory
|
|
management with incremental garbage collection, making it ideal
|
|
for configuration, scripting, and rapid prototyping.
