This can also achieve by forEach (allows you to keep that variable within the forEach’s scope)

Explaination: **getName1()** function works fine because it's being called from ***personObj***, so it has access to *this.name* property. But when while calling **getnName2** which is defined under *Object.prototype* doesn't have any proprty named *this.name*. There should be *name* property under prototype. Following is the code:

```javascript
3454+
function getName1(){
3455+
console.log(this.name);
3456+

3458+
Object.prototype.getName2 = () =>{
3459+
console.log(Object.getPrototypeOf(this).name);
3460+
}

3462+
let personObj = {
3463+
name:"Tony",
3464+
print:getName1
3465+
}
3466+
3467+
personObj.print();
3468+
Object.prototype.name="Steve";
3469+
personObj.getName2();
3470+
```
