Description
See #6658 for background.
Currently for JavaScript files we provide a very limited set of errors, mostly for syntax errors. There are a number of grammatical and type errors that would be useful to display also.
Brief notes from ad hoc discussion in the team room include:
- Move the code that flags TypeScript syntax in JavaScript files for better error handling
- Add a distinction between errors and warnings to avoid "valid" JavaScript containing errors
- Make the warnings user configurable as part of the project (i.e. may enable/disable certain warnings)
More detailed design to come...

Research direction
Start by reading issue #6658 and reviewing the current JavaScript diagnostic behavior. The notes identify TypeScript-syntax handling, error-versus-warning distinctions, and project-configurable warnings as areas to scope; completion requires a settled design before implementation can be considered done.
