6 * The opposite of `_.mapValues`; this method creates an object with the
7 * same values as `object` and keys generated by running each own enumerable
8 * string keyed property of `object` thru `iteratee`. The iteratee is invoked
9 * with three arguments: (value, key, object).
10 *
11 * @static
12 * @memberOf _
13 * @since 3.8.0
14 * @category Object
15 * @param {Object} object The object to iterate over.
16 * @param {Function} [iteratee=_.identity] The function invoked per iteration.
17 * @returns {Object} Returns the new mapped object.
18 * @see _.mapValues
19 * @example
20 *
21 * _.mapKeys({ 'a': 1, 'b': 2 }, function(value, key) {
22 *   return key + value;
23 * });
24 * // => { 'a1': 1, 'b2': 2 }
