Now that you've provided an extreme and obvious counter-example, I would still suggest that developers working on a codebase with less than 100k LoC do not in fact have to use JS, and may be selling themselves short by myopically opting for TS when more robust solutions exist. I can't give you an exact figure, but at my previous position we gradually migrated a codebase that was 10s of ks worth of JS/TS over to Purescript, and everybody's life was better off for it.
