Type annotations can add a lot of noise to the code if you don't understand what they are. Bear in mind I'm talking about someone trying to learn something. If they don't know TS you're expectng them to boil code they don't understand down to its essence.
In regards to the jQuery comparison, I'm not suggesting that someone would ask such a question of TS. All I'm saying is that there was an expectation that everything should be done in jQuery at the time.
