我在一个对象数组中有一个数组,我想从中检索一个属性.我在这里完成了它,但看起来很笨重.是否有更好的方法循环StaffList每个房间内的每个阵列？

window.onload = getInitials;
var data = {
    "room" : [
        {
            "id" : 1,
            "StaffList": [
                {                  
                  "inroom": true,                  
                  "initials": "MG"
                },
                {
                  "inroom": false,
                  "initials": "CT"
                },
                {
                  "inroom": true,
                  "initials": "MS"
                }
            ]
        },
        {
            "id" : 2,
            "StaffList": [
                {                  
                  "inroom": true,                  
                  "initials": "MG"
                },
                {
                  "inroom": false,
                  "initials": "CT"
                },
                {
                  "inroom": true,
                  "initials": "MS"
                },
                {
                  "inroom": true,
                  "initials": "MA"
                }
            ]
        }   

    ]
}

function getInitials() {
