We're WAY past the point where it is acceptable to pretend basics like map and filter are some esoteric functional thing. Every reasonable language has them, and no language without them is worth even considering.
I can't say I've actually needed to use map or filter. You can, much as people did for the last 30 years and still do with C, quite happily do this sort of stuff with a for loop...
People spent years without loops too, "quite happily" doing it with jumps. Lacking useful abstractions is not a case of preference, it is being inferior.
