JS was popular despite its lack of types, not because of them. If a typed language had been bundled into browsers from the beginning then we would not be shimming types into it with TS today (although I'm sure there would be other difficulties).

When companies started making enterprise-scale JS applications they had to solve for the type story because it is unmaintainable otherwise. TS is the winner in a long line of iterating on that problem.
