| /**
| * Creates an array of values by running each element in `collection` thru
| * `iteratee`. The iteratee is invoked with three arguments:
| * (value, index|key, collection).
| *
| * Many lodash methods are guarded to work as iteratees for methods like
| * `_.every`, `_.filter`, `_.map`, `_.mapValues`, `_.reject`, and `_.some`.
| *
| * The guarded methods are:
| * `ary`, `chunk`, `curry`, `curryRight`, `drop`, `dropRight`, `every`,
| * `fill`, `invert`, `parseInt`, `random`, `range`, `rangeRight`, `repeat`,
| * `sampleSize`, `slice`, `some`, `sortBy`, `split`, `take`, `takeRight`,
| * `template`, `trim`, `trimEnd`, `trimStart`, and `words`
| *
| * @static
| * @memberOf _
| * @since 0.1.0
| * @category Collection
| * @param {Array|Object} collection The collection to iterate over.
| * @param {Function} [iteratee=_.identity] The function invoked per iteration.
| * @returns {Array} Returns the new mapped array.
| * @example
| *
| * function square(n) {
| * return n * n;
| * }
| *
| * _.map([4, 8], square);
| * // => [16, 64]
| *
| * _.map({ 'a': 4, 'b': 8 }, square);
| * // => [16, 64] (iteration order is not guaranteed)
| *
| * var users = [
| * { 'user': 'barney' },
| * { 'user': 'fred' }
| * ];
| *
| * // The `_.property` iteratee shorthand.
| * _.map(users, 'user');
| * // => ['barney', 'fred']
