JavaScript doesn't support decorators #24745

In Deno, JavaScript decorators aren't supported. Obviously they're supported for TypeScript.

This is pretty annoying when one bundles a Deno project into one large JavaScript file to run.

The workaround is to rename the bundled files to ts instead of js.

Decorators should be supported in both TypeScript and JavaScript.

Yeah, this is just unimplemented because we're waiting for v8 to support it ("Support in pure JavaScript is waiting on implementation in V8." https://deno.com/blog/v1.40#decorators).
