Can't speak for anyone else but I started out using TypeScrip a while ago. Eventually Javascript just sort of caught up in terms of what was possible with the obvious exception of Type Casting. However after a while the annoyance of certain parts of TypeScript no longer outweighed the benefits I was getting from it, so I've dropped it and instead just use ES6/7 Javascript with Babel and in the end I'm much happier with it.
