Esbuild is cool, but if it doesn’t check the types then using Typescript is a bit pointless in the first place.

Guess a combination of esbuild during development, and tsc during commit would be the best of both worlds.

Not necessarily, TS issues are found in the editor which is where most of the use is. I don't test types only on compile but usually through VSCode itself.

Thumbs up for esbuild, it's awesome.
