Very nice. Using memoize did occur to me, but I needed an array
interface to it. Didn't think of using memoize with map, for
some reason. Thanks for the idea!
However, looking at the implementation of memoize, it seems
that it's

Today I found myself needing a lazy, caching version of map() on an
array. More precisely, given an array `T[] src` of source data and a
function func(T) that's pretty expensive to compute, return an object
`result` such that:
- result[i] == func(src[i]), for 0 ≤ i < src.length.
- If result[j]
10 matches
