function where(arr, num) {

  arr.push(num);  
  arr.sort();
 
  var newArr = arr.sort(function(a,b) {
    return a - b;
    
  });
    return newArr.indexOf(num);
  
}

where([2, 20, 10], 19);

Return the lowest index at which a value (second argument) should be inserted into an array (first argument) once it has been sorted.

First, push(num) to the end of array

I thought it would be as simple as just using sort() on the array, but it didnt do anything.

So, the sortCompare function is needed to sort numbers.

Lastly, just simply needed to return the indexOf num within the array.
