Because it looks manly.

It’s like when they show a man with perfectly round manboobs. Something primal in me would say “I’d motorboard those!”

What’s the product and what’s the field?

Oh. Hehe. You have to go there. Understood.

Then don’t go there.

I thought of Pascal, Java and C#, but pretty much any language listed here as “explicit / nominal / static” makes the cut:

Oh, so what you’re describing is strong typing. I thought it was a unique feature of Ocaml. But in reality, any strong-typed language will have this as well.

And yeah, Typescript merely “suggests” typing, and it will allow you to build the project even if you ignore the type errors. A build system refusing to, well, build, if there are typing errors usually takes care of this, but again, the dev team may as well not implement this.

What’s so special about Ocaml’s type system?
