 5 * This method is like `_.merge` except that it accepts `customizer` which
 6 * is invoked to produce the merged values of the destination and source
 7 * properties. If `customizer` returns `undefined`, merging is handled by the
 8 * method instead. The `customizer` is invoked with six arguments:
 9 * (objValue, srcValue, key, object, source, stack).
10 *
11 * **Note:** This method mutates `object`.
12 *
13 * @static
14 * @memberOf _
15 * @since 4.0.0
16 * @category Object
17 * @param {Object} object The destination object.
18 * @param {...Object} sources The source objects.
19 * @param {Function} customizer The function to customize assigned values.
20 * @returns {Object} Returns `object`.
21 * @example
22 *
23 * function customizer(objValue, srcValue) {
24 *   if (_.isArray(objValue)) {
25 *     return objValue.concat(srcValue);
26 *   }
27 * }
28 *
29 * var object = { 'a': [1], 'b': [2] };
30 * var other = { 'a': [3], 'b': [4] };
31 *
32 * _.mergeWith(object, other, customizer);
33 * // => { 'a': [1, 3], 'b': [2, 4] }
