[Deno](https://www.deno.com)
([/ˈdiːnoʊ/](http://ipa-reader.xyz/?text=%CB%88di%CB%90no%CA%8A), pronounced
\`dee-no\`) is a JavaScript, TypeScript, and WebAssembly runtime with secure
defaults and a great developer experience. It's built on [V8](https://v8.dev/),
[Rust](https://www.rust-lang.org/), and [Tokio](https://tokio.rs/).
