Javascript Question

The answer I'm getting is not the correct one (correct answer is 906609). Please help me understand where I am going wrong. I want the while loop to go from 100 to 999 while multiplying itself against the current

`i`

`// A palindromic number reads the same both ways. The largest palindrome made from the product of two 2-digit numbers is 9009 = 91 × 99.`

// Find the largest palindrome made from the product of two 3-digit numbers.

var pali = [];

function palindrome() {

for (var i = 100; i <= 999; i++) {

var counter = 100;

while (counter <= 999) {

var result = counter * i;

if (result.toString() === result.toString().split("").reverse().join("")) {

pali.push(result);

}

counter++;

}

}

return pali[pali.length - 1];

}

console.log(palindrome());

You're going to have to sort the array in ascending order if you want the last one to be the highest:

```
pali.sort(function(a, b){return a-b});
```

Using that, I get 906609.
