Validate JS file against typings?

[unional]

With salsa provides typings support to javascript files, is there a way on the cli to use salsa to get a list of warning as in the language service?

If we can, we can use it to much quicker validate typings for typings authors by re-using test code available in the source package.

This could have a significant impact on typescript adoption considering this use case:

Help package author to maintain their own .d.ts file.

Using this feature, package author can still write code in js and easily verify if their typings need to be updated.

We now have the checkjs option for now which allows for validating types in JavaScript as specified by JsDoc comments and basic inference. No plans to add any type of dynamic/runtime verification at this point, so closing this issue.
