**Tell us what’s happening:**

I wrote this code on website and it shows infinite looping but I wrote the code on vs code it ran can someone tell me why

**Your code so far**

```
function largestPalindromeProduct(n) {
let n1=1,n2=1;let product=1;let i;
for ( i = 1; i < n; i++)
{n1 = n1 * 10 ;}
for ( i = 1; i <=n; i++)
{n2 = n2 * 10 ;}
for ( i = n1; i < n2; i++)
{
for (let j = n1; j < n2; j++)
{
let prod = i * j;
let prod1=prod;
let sum=0;
while(prod1>0)
{
sum=(sum*10)+(prod1%10);
prod1=prod1/10;
}
if(sum==prod && prod>product)
product=prod;
}
}
return product;
}
largestPalindromeProduct(3);
```
