合并两个对象，并去重

var ss={
    name:'你不好',
    id:123
}
var bb={
    name:'你好',
    id:520,
    year:'1212',
    he:'王八蛋'
}
//ss=Object.assign(ss,bb);
//console.log(ss)//{name: "你好", id: 520, year: "1212", he: "王八蛋"}


var cc={};
for(var i in bb){
    for(var o in ss){
        if(i==o){
            cc[i]=bb[i]
        }
    }
}
console.log(cc) //{name: "你好", id: 520}
