Typescript errors not being thrown

Hi, first of all I would like to thank @evanw for the effort he puts on this project.

I'm finding that esbuild shallows typescript errors. Walked through the documentation and couldn't see anything related. Log level param won't make any effect on this.

node version: 14.17.5
npm version: 7.24.0
esbuild version: 0.13.1

Example script:
esbuild src/index.ts --bundle --outfile=public/index.js

Example code:

  const test: number = 'An extremely fast JavaScript bundler'
  console.log(test)

Maybe am I missing out something? Is this a known Issue? Didn't find anything related on the Issues either.
Thanks!

From esbuild's documentation on TypeScript:

However, esbuild does not do any type checking so you will still need to run tsc -noEmit in parallel with esbuild to check types. This is not something esbuild does itself.

Replicating the TypeScript type system is out of scope. Closing.

Thank you
