I'm a fan of TS, and have no issue with people's opinions on programming languages. But come on, the whole "built in a week" thing is pretty tired at this point. There have been many, many major iterations on Javascript since the 90s. There's nothing inherently wrong with vanilla JS these days. It has a few quirks like every language does, but overall generally does what you expect it to do.
