As lua.org was saying, Lua is a powerful, fast, lightweight, embeddable scripting language. Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics.
Lua is small: the Lua interpreter easily fits in under 100 kilobytes including the base libraries.
Lua is fast: independent benchmarks show that Lua is often amongst the fastest interpreted dynamic languages. The Lua interpreter has been extensively tuned for high performance.

for Lua programming and run codes on ESP8266 over-the-air.
