Where do belong the beginning or end of the array

1

This works for everything but the num at the beginning and end of the array.
//Where do I belong
function getIndexToIns(arr, num) {
// Find my place in this sorted array.
arr.sort(); //sort the array
for (var a = 0; a < arr.length; a++){

  if ( arr[a] >= num) {
    return parseInt(a);

}

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

Sometimes I find it helps to use the console.log to see what values certain things are returning. For instance your

arr.sort();

is returning:

[20, 3, 3, 5]

I’m not sure this is really what your looking for.

Therefore when you loop through the array and:

return parseInt(a)

you get:

0 & 3

which are the positions in the arr that meet your if statement.

Hi joelpeyton,
Thanks for the tip. I assumed that the table was sorted the way I wanted it and it was not.
