It features (from the website):
- Secure by default. No file, network, or environment access, unless explicitly enabled.
- Supports TypeScript out of the box.
- Ships only a single executable file.
- Has built-in utilities like a dependency inspector (deno info) and a code formatter (deno fmt).
- Has a set of reviewed (audited) standard modules that are guaranteed to work with Deno
Its an interesting project, and maybe one day may start to replace Node, but its still too early to tell.
