方法一:不改变原来对象
let item = {
name:‘张三‘,
age:‘18‘,
gender:‘男‘
};
console.log(item) // {age: "18",gender: "男",name: "张三"}
let { age,...params } = item;
console.log(item) // {age: "18",gender: "男",name: "张三"}
console.log(typeof params.age) // undefined
console.log(params) // {gender: "男",name: "张三"}
方法二:直接改变对象
let item1 = {
name:‘张三‘,
age:‘18‘,
gender:‘男‘
};
console.log(item1) // {age: "18",gender: "男",name: "张三"}
delete item1.name;
console.log(typeof item1.name) // undefined
console.log(item1) // // {age: "18",gender: "男"}
