 	Luau is a high-performance managed language with a fast bytecode compiler and interpreter, and an optimized, incremental garbage collector. Its optional JIT compiler runs on x64 and arm64, and supports plugins that extend native code generation to any embedder-defined types.

 	Luau has a state-of-the-art gradual type system with features like [type refinements](./types/type-refinements) and [type functions](./types/type-functions). This system is powered by an ambitious and powerful type inference engine that aims to both rule out program errors, _and_ provide autocomplete with minimal annotations.

 	<ColoredCard title="Accessibility" icon="pen" color="purple">
 	Luau is designed to be easy-to-learn, and easy-to-use over time. The syntax of the language is small and easy to pick up, and the semantics of the language should be broadly unsurprising to most programmers, with recursive functions, conventional loops and branching, and so forth.

 	Luau aims to be pleasant and productive to use, and to make programming as fun as it can be! Besides the language itself, we're building a full suite of developer tools: package management, linting, code transformation, documentation generation, and servers for editing and debugging code.
