//使用递归函数进行深拷贝 //函数拷贝 const copyObj = (obj = {}) => { //变量先置空 let newobj = null; //判断是否需要继续进行递归 if (typeof (obj) == 'object' && obj !== null) { newobj = obj instanceof A
1、赋值 修改新对象原来的对象会发生改变(改变存储空间，联动改变) let person = { name: 'Tom', age: 12, hobby: ['音乐', '动漫'] } let copyObj = person; copyObj.name = '小明'; copyObj.hobby[0] = '看电视'
let obj = { job: { address: 'shenzhen', salary: '20k' }, name: 'zhang', age: 22 } // 第一种（函数和正则不可以） // let obj1 = JSON.parse(JSON.stringify(obj)) // obj.name = 'mm' // console.log(obj1); // co
