/**

 * 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).

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.
