Well yes, surely because you’re not designing your system around the type system. You need to architect your project to lean heavily on types, pattern matching, etc to actually gain the benefits. If you move a JS project to TS and just rename the files, yeah there’s going to be no difference, you must reengineer the entire codebase to leverage the type system.

Personally, after moving to TS I’ve been completely sold on types and am currently planning to migrate my app to F# so I can gain even more benefit.
