loadsh中深拷贝,合并对象

合并对象

const 合并对象 = _.merge(对象1,对象2) 在merge中的对象属性重复时，后面的会覆盖前面的。

<body>
    <script src="https://cdn.jsdelivr.net/npm/lodash@4.17.21/lodash.min.js"></script>
    <script>
        const obj1 = {
            name: 'lisi',
            hobby: '跳舞'
        }
        const obj2 = {
            nikename: '李四',
            age: 19
        }
        const obj = _.merge(obj1, obj2)
        console.log(obj); //{name: 'lisi', hobby: '跳舞', nikename: '李四', age: 19}
    </script>
</body>

对象深拷贝

const 拷贝后的对象 = _.cloneDeep(被拷贝的对象)

    <script src="https://cdn.jsdelivr.net/npm/lodash@4.17.21/lodash.min.js"></script>
    <script>
        const obj = {
            name: '李四',
            age: 18
        }
        const newObj = _.cloneDeep(obj)
        newObj.name = '张三'
        console.log(obj);
        console.log(newObj);
    </script>
