The same reason it would be a good thing to use JS under any circumstances: there's already a huge supply of developers familiar with it and its ecosystem, it's available on pretty much every platform (now including at least one dedicated unikernel environment), it's a natural fit for web application development, and so on.

It's clear why unikernels and OCaml go together so nicely: immutability is a concept central to them both.

That said, the affordances of using a unikernel seems fairly orthogonal to the choice of language, IMO.

And now so is OCaml, Elm, PureScript, C++, and anything else that compiles to JS.

Now that other languages are beginning to compile to JS, they are also becoming increasingly natural for web app development.

This is definitely true.
