You're entitled to your opinion, but for many people (me being one) first-class TypeScript support is absolutely a compelling feature. I may not choose Angular for every project, but I would certainly never again use untyped JavaScript over TypeScript, for an app of any size, unless there was some unusual and very compelling reason. (And it would have to be a really unusual reason; I can't even think of a hypothetical one.) In my own experience, TypeScript is a huge advance over JavaScript without types, in both productivity (how quickly functionality gets implemented) and reliability (how many bugs ever make it all the way to a customer). I will spice up that factual statement with a bit of speculation that will perhaps be more controversial: in my experience watching other developers move to TypeScript, I think the productivity and reliability gains generally apply to their work too, whether or not they personally like TypeScript.
