It's interesting how OP says people are moving towards more functional-style Javascript, but also dismisses statically typed Javascript. The two work really well together.
I'm convinced functional style is a fad and nothing will change my mind. The style has been around for forever and there's a good reason most languages are still OOP.
We're in the phase of the hype loop where everyone assumes language designers from 15 years ago are idiots. In another few years everyone will be talking about the revival of OOP
Functional style programming is not a fad so much as a different taste. Not everyone will always have the same tastes. It's like peanut butter and chocolate: you can love only one or the other, you can also love both or know that each has different strengths for different needs (projects/desserts).
I can understand if people think it's a fad, but I would expect people who _do_ like it to also like TypeScript :)
That said, if someone thinks language designers from the past are idiots, then they also shouldn't like functional programming, as it's at least as old.
