Mapcar applies function fn to elements of lists with same index.
Each application result is put into resulting list.
Length of resulting list is the length of the shortest list argument.
Came from lisp.
npm i mapcar --save
bower i mapcar --save
mapcar(sum, [1,2,3,4], [1,2]);
// returns
[2,4]
function sum(array) {
return array.reduce(function(value, item) {
return value + item;
}, 0);
}MIT
