A modern runtime for JavaScript and TypeScript.

This commit changes "deno repl" command to run with no permissions by default and accept "--allow-*" flags. This change is dictated by the fact that currently there is no way to run REPL with limited permissions. Technically it's a breaking change in the CLI command, but there's agreement in the team that it has merit and it's a good solution. Running just "deno" command still starts the REPL with full permissions allowed, but now a banner is printed to inform users about that: |

- Ships only a single executable file.
- Built-in utilities.
- Set of reviewed standard modules that are guaranteed to work with Deno.

Getting Started
Try running a simple program:
deno run https://deno.land/std/examples/welcome.ts
Or a more complex one:
const listener = Deno.listen({ port: 8000 });
console.log("http://localhost:8000/");
for await (const conn of listener) {
serve(conn);
}
async function serve(conn: Deno.Conn) {
for await (const { respondWith } of Deno.serveHttp(conn)) {
respondWith(new Response("Hello world"));
}
}
You can find a deeper introduction, examples, and environment setup guides in the manual.
The complete API reference is available at the runtime documentation.
