js如何拼接对象相同的数组

Question

有以下3个数组
arry1{
create_user: "a"
data: 3
department: "a"
engineers: "a"
evaluate_userlist: "a"
hosp_name: "a"
id: "a"
inner_status: "a"
manager_id: "a"
manager_idlist: "a"
}
arry2{
id: 86
isAdmin: false
mobile: "15757116643"
name: "minjiezhao"

}
arry3{
engineers: "22我是"
evaluate_userlist: "1"
hosp_name: "大华医院"

}

需要生成的数组

arry4{
create_user: "a"
data: 3
department: "a"
engineers: "22我是"
evaluate_userlist: "1"
hosp_name: "大华医院"
id: "86"
inner_status: "a"
manager_id: "a"
manager_idlist: "a"
}

等于是把其他不同数组的相同的对象名字，赋值给第一个数组，需要去重判断，有些在多个数组中都有。

Answer 1

var arry4 = Object.assign({},arry1,arry2,arry3);
