How is this different from `tsc && node dist/run.js`?

1. It’s much faster. 2. It won’t catch type errors.

Regarding #2, I assume that things are set up so that type errors are caught in some other way, such as in CI or in a precommit hook.

What I do is run esbuild and tsc (with no emit) in parallel in watch mode. That way, I get fast rebuilds and iterations, but still eventually see the errors spit out.

My code editor catches 90% of the errors, but it’s definitely nice to have tsc catch the rest earlier than the CI process.

With or without strict mode enabled?

It's a lot faster (runs in 0.1 seconds) so it doesn't affect our iteration speed at all.
