# Where do I belong-partial output

Tell us what’s happening:

``````
function getIndexToIns(arr, num) {
// Find my place in this sorted array.
var arr1 = arr.sort();
var i;
for( i = 0;i<arr1.length ; i++) {
if(arr1[i] >= num){
break;
}
}
if(i==arr1.length){
return i++;
}else if(i < arr1.length) {
return i;
}

}

getIndexToIns([3, 10, 5],  3);

It deals okay with no repetetions but not with repetions why??

You have the right idea. The problem is your sort function. By default, sort converts to strings and sorts alphabetically. So, `[5, 3, 20, 3]` would be sorted as `[20, 3, 3, 5]` - not what you want.

From the Mozilla page, here is an example of sorting numbers:

``````var numbers = [4, 2, 5, 1, 3];
numbers.sort(function(a, b) {
return a - b;
});
console.log(numbers);

// [1, 2, 3, 4, 5]
``````

Also, the sort function sorts in place so you can just apply it to arr directly:

``````arr.sort(function(a, b) {
//...
``````

and then just use arr everywhere. Yes, it gets a little confusing. Some methods return their value, some do it in place.

You can use the shorter version of sort.

``````var numbers = [4, 2, 5, 1, 3];
numbers.sort((a,b) => a - b );

console.log(numbers);
