75+ * 递归合并 `source` 来源对象自身的可枚举属性（包含 `Symbol` 属性）到 `object` 目标对象。
76+ *
77+ * 与 `merge` 方法的区别：
78+ *
79+ * 1. 不合并数组，如果只传入 `2` 个参数，同 `merge(obj, src, merge.NOT_MERGE_ARRAYS)`
80+ * 2. 不支持自定义赋值函数和获取对象键，但支持多个来源对象参数
81+ *
82+ * @alias module:Object.mergeObject
83+ * @since 1.15.0
84+ * @param {Object | Array} object 目标对象。
85+ * @param {...object} args 展开的来源对象。
86+ * @returns 目标对象。
87+ * @example
88+ *
89+ * mergeObject({c: 3}, {e: 5}); // { c: 3, e: 5 }
90+ * mergeObject({ a: 1 }, { a: undefined, b: undefined }); // { a: 1, b: undefined }
91+ * mergeObject({ a: 1 }, { a: undefined, b: undefined }, {c:'x'}); // { a: 1, b: undefined, c: 'x' }
92+ *
93+ * const source = {
94+ * a: [{b: 2}, {d: 4}]
95+ * }
96+ * const otherSource = {
97+ * a: [{c: 3},{e: 5}]
98+ * }
99+ * mergeObject({}, source, otherSource); // { a: [{c: 3}, {e: 5}] }
