LuaJIT is a Just-In-Time (JIT) compiler for the Lua programming language, offering a high-performance interpreter and trace compiler. It includes an FFI library for calling C code, a profiler, and DynASM for code generation.

Use cases

speed up Lua scripts with JIT compilation
embed a fast Lua runtime in a C application
call C libraries from Lua without bindings via FFI
profile and optimize Lua code performance
generate machine code dynamically with DynASM

When to choose

you need a very fast Lua interpreter for games, servers, or embedded scripting
you want low-overhead FFI to C libraries
you need a small, portable scripting VM across POSIX and Windows

When to avoid

you need full Lua 5.3/5.4 language features
you require a pure-JavaScript or sandboxed environment
you need a license other than MIT for strict compliance review
