/**

 * This method is like `_.assign` except that it recursively merges own and

 * inherited enumerable string keyed properties of source objects into the

 * destination object. Source properties that resolve to `undefined` are

 * skipped if a destination value exists. Array and plain object properties

 * are merged recursively. Other objects and value types are overridden by

 * assignment. Source objects are applied from left to right. Subsequent

 * sources overwrite property assignments of previous sources.

 *

 * **Note:** This method mutates `object`.

 *

 * @memberOf _

 * @since 0.5.0

 * @category Object

 * @param {Object} object The destination object.

 * @param {...Object} [sources] The source objects.

 * @returns {Object} Returns `object`.

 * @example

 *

 * var object = {

 *   'a': [{ 'b': 2 }, { 'd': 4 }]

 * };

 *

 * var other = {

 *   'a': [{ 'c': 3 }, { 'e': 5 }]

 * };

 *

 * _.merge(object, other);

 * // => { 'a': [{ 'b': 2, 'c': 3 }, { 'd': 4, 'e': 5 }] }
