mapfn

mapfn(fn)
      

Return a function that takes a sequence xs as its argument and returns a sequence of the results of applying fn to each element of xs.

Examples:

let doubler = mapfn(^(x) x * 2)
doubler([1,2,3,4,5])
// [2, 4, 6, 8, 10]

let adder = mapfn(add)
adder([1, 2, 3], [4, 5, 6])
// [5, 7, 9]
