vue如何删除数组对象中的某一个属性

数据如下，我想删除数组中所有的value字段

这么写不太行，求详细解释

let arr=[{
        name:"张三",
        age:45,
        money:100,
        girlFriend:["华为","淘宝","小米"]
    },
    {
        name:"李四",
        age:23,
        money:22,
        girlFriend:["华为","淘宝","小米"]
    }]
    //删除每个对象的girlFriend
    arr.forEach((ele,index)=>{
        if (ele.girlFriend){
            delete  ele.girlFriend
        }
    })
    console.log(arr)

this.list.map(item=>{
return delete item.value
})
console.log(this.list)
