Even less lucky: coding in vanilla JavaScript. In the days before Definitely Typed, I still got a lot of mileage out of types in my code alone. It felt immensely more apt then using JSDoc to document types everywhere. In my experience, even if you don't have types for a third-party library, you can get away with adding types for the interfaces you care about.
