Bug with Sorting Arrays Where do I Belong

Tell us what’s happening:
My code worked for every test case except getIndexToIns([5, 3, 20, 3], 5) (rather than returning 2, my function returns 0).

As part of debugging, I checked the value of sorted with the above input, and I see that this array does not sort in order.

Can someone help me understand what’s going on?

Your code so far

function getIndexToIns(arr, num) {
  // Find my place in this sorted array.
  var sorted = arr.sort();
  var i = 0;
  while (i < sorted.length){
    if (sorted[i]<num){
    else {
originally the part below was "return i;"— I changed it for debugging purposes

getIndexToIns([5,3,20,3], 5);

Link to the challenge:

i think your sort method is not working? It returns this:
[ 20, 3, 3, 5 ]

which is definitely not sorted. You should re-write your sort like this instead:

var sorted = arr.sort( (a,b) => (a-b));

@wdudek It returns what @hbar1st says and the reason is the default sort method treats numbers as strings, so “20” is less than “3”.
