> And I'm actually quite happy that most Deno projects don't have a custom testing and linting setup.

I feel similarly. The standard configurations (e.g. tsconfig, linting, formatting) and bolts-included tooling (test, lint, fmt, etc.) are what make Deno so great for developers.

I've started using Deno in my spare time for various projects - and it just _feels_ more productive. I go from idea to testing TypeScript in minutes - which never happened in Node land.
