# Coi

> Coi is a statically-typed, component-based language for building reactive web apps that
> compile to WebAssembly. It looks JSX-like but is NOT JavaScript or TypeScript: it has static
> types, explicit ownership (copy / reference / move), no garbage collector, no virtual DOM,
> and fine-grained reactivity. Source files use the `.coi` extension.

For AI assistants and agents: the complete, self-contained language and API reference is in
[llms-full.txt](llms-full.txt). If the Coi compiler is installed, run `coi llms` to print that
full context to stdout, or `coi llms --path` to print its file path. Load it before writing or
fixing Coi code so you use correct Coi syntax instead of JavaScript/TypeScript idioms.
