i don't understand this part of the diff
isn't it the same code as the map but written with an each and a counter
that counts side effects? if so i would prefer the map back again, the counter
thingy is a bit odd
to speed up the code you can also put the `if (!databases.paginated(page,
perPage).length) {` above the other code and just return early
