JS对象合并方法

let obj1={
            department:'编号',
            title:'题名',
        };
        let obj2={
            deveId:'1385118536590883515',
        };

        //方法一：利用扩展运算符
        let obj3={...obj1,...obj2};
        console.log(obj3);

        //方法二：利用ES6 Object新增assign方法
        let obj4=Object.assign({},obj1,obj2);
        console.log(obj4);
