LuaJIT is a B<Just-In-Time Compiler> (JIT) for the E<rchevron> Lua
programming language. Lua is a powerful, dynamic and light-weight
programming language. It may be embedded or used as a general-purpose,
stand-alone language.
LuaJIT is Copyright E<copy> 2005-2017 Mike Pall, released under the
E<rchevron> MIT open source license.

Lua
LuaJIT has been successfully used as a B<scripting middleware> in
games, appliances, network and graphics apps, numerical simulations,
trading platforms and many other specialty applications. It scales from
embedded devices, smartphones, desktops up to server farms. It combines
high flexibility with E<rchevron> high performance and an unmatched
B<low memory footprint>.
LuaJIT has been in continuous development since 2005. It's widely
considered to be B<one of the fastest dynamic language
implementations>. It has outperformed other dynamic languages on many
cross-language benchmarks since its first release E<mdash> often by a
substantial margin.
For B<LuaJIT 2.0>, the whole VM has been rewritten from the ground up
and relentlessly optimized for performance. It combines a B<high-speed
interpreter>, written in assembler, with a B<state-of-the-art JIT
compiler>.
An innovative B<trace compiler> is integrated with advanced, SSA-based
optimizations and highly tuned code generation backends. A substantial
reduction of the overhead associated with dynamic languages allows it
to break into the performance range traditionally reserved for offline,
static language compilers.
