es6删除数组元素或者对象元素

一，删除数组元素
let arr = [
{name:’黎明’,id:21111},
{name:’王小二’,id:1111},
{name:’大小二’,id:3222}
]
arr.splice(arr.findIndex(item => item.id === 3222), 1)

arr.filter(obj=>obj.id!==3222)

二，删除对象元素
let arr = {
name: ‘黎明’,
id: 1111,
age: 24
};

方法1：

const personUnkonwAge = (({name, id}) => ({name,id}))(arr)
console.log(personUnkonwAge)
console.log(arr)

方法二：

let {name, …personUnknowName} = arr
console.log(personUnknowName)
