Question

let allLamps = [];      

// Object Constructor Function that will add new obj to array

function Object (serial, type, od, ol, arc) {
    this.serial = serial;
    this.type = type;
    this.od = od;
    this.ol = ol;
    this.arc = arc;
};       

const obj1 = new Object(1,"g51",75,95,46);
const obj2 = new Object(2,"g38",75,95,46);
const obj3 = new Object(3,"9k",57,67,27);

function push(obj) {
    allLamps.push(obj);
}

push(obj1);
push(obj2);
push(obj3);

因此，如果将数组allLamps记录到控制台，我会得到所有的对象：
```
console.log(allLamps)
```

我想访问每个属性，如：

const getAll = allLamps.map(function(obj){
     return obj.serial;
});

或

for(var i = 0; i < allLamps.length; i++){
    return allLamps[i].serial;
}

但似乎我得到了不确定。注意我还在学习基础知识。我知道我做错了什么。我感谢任何解决方案。即使我这样做：
```
for (var i = 0; i < allLamps.length; i++ {
    return allLamps[i];
}
```

我只得到我的一个物体，而不是所有物体。

字面定义数组

const lamp = (serial, type, od, ol, arc) => lamps.push({serial, type, od, ol, arc});
const lamps = [];
lamp(1,"g51",75,95,46);
lamp(2,"g38",75,95,46); 
lamp(3,"9k",57,67,27);

作为推送数组项目

const lamp = (serial, type, od, ol, arc) => ({serial, type, od, ol, arc});
const lamps = [];
lamps.push(lamp(1,"g51",75,95,46));
lamps.push(lamp(2,"g38",75,95,46)); 
lamps.push(lamp(3,"9k",57,67,27));

或

function Lamp (serial, type, od, ol, arc) {
    this.serial = serial;
    this.type = type;
    this.od = od;
    this.ol = ol;
    this.arc = arc;
};
const allLamps = [];
lamps.push(new Lamp(1,"g51",75,95,46));
lamps.push(new Lamp(2,"g38",75,95,46)); 
lamps.push(new Lamp(3,"9k",57,67,27));

或

const lamp = (serial, type, od, ol, arc) => ({serial, type, od, ol, arc});
const lamps = [
    [1,"g51",75,95,46],
    [2,"g38",75,95,46],
    [3,"9k",57,67,27]
 ].map(data => lamp(...data));
