/**
 * Produce a new array by passing each value in the input `collection` through a transformative

 * `(value, index, collection)`.
 *
 * @name map
 * @api public
 * @param {Function} iterator The transformer function to invoke per iteration.
 * @param {Array} collection The collection to iterate over.
 * @return {Array} A new array containing the results of each `iterator` invocation.
 * @example
 * var square = function(x) { return x * x; };
 *
 * map(square, [1, 2, 3]);
 * //=> [1, 4, 9]
