      6  * This method is like `_.assignIn` except that it accepts `customizer`
      7  * which is invoked to produce the assigned values. If `customizer` returns
      8  * `undefined`, assignment is handled by the method instead. The `customizer`
      9  * is invoked with five arguments: (objValue, srcValue, key, object, source).
     10  *
     11  * **Note:** This method mutates `object`.

     18  * @param {Object} object The destination object.

     20  * @param {Function} [customizer] The function to customize assigned values.
     21  * @returns {Object} Returns `object`.
