<pre><code>function Person(name,dob){
this.name=name;
this.birthday=new Date(dob);
this.calculateAge = function(){
const diff = Date.now()-this.birthday.getTime();
const ageDate = new Date(diff);
return Math.abs(ageDate.getUTCFullYear()-1970);
}
const brad11 = new Person('Brad','1993-08-29');
</code></pre>The above code is working fine the confusion here is in the line of return statement I am unable to understand the logic that why we are multiplying ageDate with getUTCFullyear and then subtracting 1970 from it .


```

The above code is working fine the confusion here is in the line of return statement I am unable to understand the logic that why we are multiplying ageDate with getUTCFullyear and then subtracting 1970 from it .

It is not, because, in fact, you opened another topic about why it is not working. Please refrain from making false statements.
In addition, your braces do not match. No one would be able to execute your code like that. I recommend creating a codepen, which you confirm working before telling us that the code is working, and then sharing the pen instead of just the code.
