Actually it's even `map((element, index, array) => parseInt(element, index, array))`. In this case `parseInt` does not use third argument but with other functions it might even make more chaos.

`Array.map` function API was badly designed. I'd like to know who I should to blame for that design.

I don't think the API is that bad, just that writing "point free" in any language with loose typing is dangerous.
