In addition to a completely custom front end that implements parsing, linting and type checking, Luau runtime features new bytecode, interpreter and compiler that are heavily tuned for performance. Luau interpreter can be competitive with LuaJIT interpreter depending on the program. An optional component for manual Just-In-Time compilation is also available for x64 and arm64 platforms, which can considerably speed up certain programs.
