根据对象里面某个值做判断，当有id重复的时候，当前对象覆盖之前的对象

Question

let obj = {
    column:{
        __id:'1',
        align: "center"
        className: "test-name"
        key: "singlePrice",
        ....
    },
    index: 0
    row:{
        applyNum: 1
        brandName: "世达"
        brandPk: "ca36dcac632c4dc0b704aaa88ec01fdb"
        categoryName: "物料类1",
        ...
    }
}

let obj2 = {
    column:{
        __id:'1',
        align: "center"
        className: "test-name"
        key: "singlePrice",
        ....
    },
    index: 1
    row:{
        applyNum: 2
        brandName: "11"
        brandPk: "ca36dcac632c4dc0b704aaa88ec01fdb"
        categoryName: "物料类2",
        ...
    }
}

先有一个obj ，当我获取了第二个obj2的时候，里面column.__id是一样的，怎么样判断让obj2覆盖obj的呢

Answer 1

Object.assign(obj,obj2) 对象合并
