Description

I'm confused why this example starts off talking about linting and then the example it gives is called check-types and sounds very much like typechecking.

Unsure which one is right but it feels like it'd be better to be consistent?

Alternatively you could change the above example to be typechecking instead, but based on this dissonance I'm actually a little confused by your example. Using Internal Packages™

since a type checker doesn't need to wait for outputs in dependencies to run successfully

could be true. Not using Internal Packages, where the output is .d.ts files, it would seem like you definetly can't typecheck package A if package B could be changing .d.ts files.

This runs your tasks in parallel - but doesn't account for source code changes in dependencies. This means you can:

1. Make a breaking change to the interface of your `ui` package.
2. Run `turbo check-types`, hitting cache in an application package that depends on `ui`.
2. Run `turbo lint`, hitting cache in an application package that depends on `ui`.

This is incorrect, since the application package will show a successful cache hit, despite not being updated to use the new interface. Checking for TypeScript errors in your application package manually in your editor is likely to reveal errors.

I guess if I change to lint here, now these references to Typescript need changing. So probably need to understand intent better to proceed.

Technically, TypeScript as a type checker is a linter. But I can see how that would be confusing. Would this change be clearer?

Yeah that works!

But I guess it feels like a more confusing example given my comment above:

When NOT using Internal Packages, where the output of each package is .d.ts files, it would seem like you definetly can't start typechecking package A (which depends on B) until package B emits its .d.ts files

Sorry, missed that. You're right, let's swap the example to being lint.
