js两个list根据key合并

let arr2 = [
        {
            "id": "101",
            "rightname": "ruguo",
            'a': '123',
            "b": '466',
            "c": '789',
        }, {
            "id": "102",
            "rightname": "hello",
        },
        {
            "id": "103",
            "rightname": "noshi"
        }
    ]
    let arr1 = [
        {
            "id": "101",
            "path": "/a",
            "icon": 'icon-add',
        }, {
            "id": "102",
            "path": "/b",
            "icon": 'icon-edioter',

        },
        {
            "id": "103",
            "path": "/c",
            "icon": 'icon-edioter',
        }
    ]

    for (var i = 0; i < arr2.length; i++) {                             
        var aa = arr2[i];
        
        var aid = aa.id
        for(var w = 0; w < arr1.length; w++){
            var bb = arr1[w]
            var bid = bb.id;
            if(bid == aid){  //id相同开始合并
                //迭代arr1里面的json对象
                for(var e in bb){
                if(e == 'id') continue;
                aa[e] = bb[e];
                }
                
            }
        }
        
        
    
        
    }
    console.log(arr2);

arr1拼接到arr2中
