+/**
+ * This method is like `_.assign` except that it accepts `customizer`
+ * which is invoked to produce the assigned values. If `customizer` returns
+ * `undefined`, assignment is handled by the method instead. The `customizer`
+ * is invoked with five arguments: (objValue, srcValue, key, object, source).
+ *
+ * **Note:** This method mutates `object`.
+ *
+ * @static
+ * @memberOf _
+ * @since 4.0.0
+ * @category Object
+ * @param {Object} object The destination object.
+ * @param {...Object} sources The source objects.
+ * @param {Function} [customizer] The function to customize assigned values.
+ * @returns {Object} Returns `object`.
+ * @see _.assignInWith
+ * @example
+ *
+ * function customizer(objValue, srcValue) {
+ * return _.isUndefined(objValue) ? srcValue : objValue;
+ * }
+ *
+ * var defaults = _.partialRight(_.assignWith, customizer);
+ *
+ * defaults({ 'a': 1 }, { 'b': 2 }, { 'a': 3 });
+ * // => { 'a': 1, 'b': 2 }
