js修改对象中属性的几种方法

修改对象中的属性

1.正则替换

let a = {
    name:'java',
    age:18
}
const b = JSON.parse(JSON.stringify(a).replace(/name/g,'job'))

2.delete再手动添加

const a = {
    name:'java',
    age:18
}
let c = {...a}
delete c.name
c ={job:'java',...c}

3.自动添加再delete

const a = {
    name:'java',
    age:18
}
let d = {...a}
d.job=d.name
delete d.name
