Deno is a simple, modern and secure runtime for JavaScript, TypeScript, and WebAssembly that uses V8 and is built in Rust. Deno comes with a manual which contains more in depth explanations about the more complex functions of the runtime, an introduction to the concepts that Deno is built on, details about the internals of Deno, how to embed Deno in your own application and how to extend Deno using Rust plugins. Next to the Deno runtime, Deno also provides a list of audited standard modules that are reviewed by the Deno maintainers and are guaranteed to work with a specific Deno version. These live in the denoland/deno_std repository.
