| 6 | * Creates an object with the same keys as `object` and values generated |
| 7 | * by running each own enumerable string keyed property of `object` thru |
| 8 | * `iteratee`. The iteratee is invoked with three arguments: |
| 9 | * (value, key, object). |

| 13 | * @since 2.4.0 |
| 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 _.mapKeys |
| 19 | * @example |
| 20 | * |
| 21 | * var users = { |
| 22 | * 'fred': { 'user': 'fred', 'age': 40 }, |
| 23 | * 'pebbles': { 'user': 'pebbles', 'age': 1 } |

| 27 | * // => { 'fred': 40, 'pebbles': 1 } (iteration order is not guaranteed) |

| 29 | * // The `_.property` iteratee shorthand. |
