/** |
|
* The opposite of `_.mapValues`; this method creates an object with the |
|
* same values as `object` and keys generated by running each own enumerable |
|
* string keyed property of `object` thru `iteratee`. The iteratee is invoked |
|
* with three arguments: (value, key, object). |

|
* @category Object |
|
* @param {Object} object The object to iterate over. |
|
* @param {Function} [iteratee=_.identity] The function invoked per iteration. |
|
* @returns {Object} Returns the new mapped object. |
|
* @see _.mapValues |
|
* @example |
|
* |
|
* _.mapKeys({ 'a': 1, 'b': 2 }, function(value, key) { |
|
* return key + value; |
|
* }); |
|
* // => { 'a1': 1, 'b2': 2 } |
