js删除对象中的某一个字段的方法
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"}原文：https://www.cnblogs.com/dqzpq/p/14964476.html
