In most programming languages JS style APIs (i.e. give me anything and I will try to interpret it somehow in an undocumented or poorly documented way) are antipatterns. TS is often bringing sanity to libraries that switch from JS to TS. I think TS team is doing really great job. I would not call it standing on the shoulders of predecessor, more like trying to build something stable on the swamp. JS definitely does not have a positive influence on TS. TS is not a great programming language, but it is really great accomplishment considering that it supports and extends JS in a such good way.
