/**
 * Creates a new list out of the two supplied by applying the function to each

 * length of the shorter of the two input lists.
 *
 * @param {Function} fn The function used to combine the two elements into one value.
 * @param {Array} a The first array to consider.
 * @param {Array} b The second array to consider.
 * @return {Array} The list made by combining same-indexed elements of `a` and `b`
 *         using `fn`.
 * @example
 *
 *      var f = (x, y) => {
 *        // ...
 *      };
 *      zipWith(f, [1, 2, 3], ['a', 'b', 'c']);
