**Tell us what’s happening:**

How do I sort the numbers in the array, .sort won’t work.

How can i get the algorithm to work? I’ve looked for help online to no avail.

thank!

Just need some help understanding why it won’t work and in what instance the sort method would work.

**Your code so far**

```
function getIndexToIns(arr, num) {
var array = arr.push(num);
array.sort(function(a, b) {
return a - b;
});
for (var i=0; i<array.length; i++) {
if (array[i] == num) {
return i;
}
}
}
getIndexToIns([40, 60], 50);
```
