HoFs are not array comprehensions and array comprehensions aren't supported in ES6.

Neither of these is a claim I made so I'm not sure why you feel the need to point these out.
However native HoF obviate much of the need for comprehensions, especially combined with terser "arrow functions". Languages like Smalltalk or Ruby do just fine without comprehensions for instance.
