I'm in the same boat, I still like the plain old vanilla JS I do see the benefits of Typescript and all but I don't know I have been doing JS since I was 10 years old so I guess it's something that comes from my childhood haha. I just love JS in any fashion, it's a love relationship since the beginning and way back then I always saw that there was huge value around JS but never imagined back then that we would get to were we are today, back then Flash was the big deal and it was doing the more advanced functionality in the front-end could never imagined that Shockwave, Flash would all get basically banned due to security. Interesting turn around for JS and the open source nature it has always had since its infancy with the Mozilla Browser.
