I am attempting to output a pattern of numbers that takes an input and descends then ascends back up to the original number one digit at a time

I am trying to write a problem that outputs a similar pattern to this using recursion.

cascade(12345) //should print

12345
1234
123
12
1
12
123
1234
12345

I figured out how to do the descending part but I am stuck on how to ascend back up! This is what I have so far...

function cascade(number) {
  let strNum = number.toString()
  let numLength = strNum.length;
  let lengthTracker = numLength
  let hasHit1 = false;
  console.log(strNum)
  if (lengthTracker > 1 && hasHit1 === false) { 
    strNum = strNum.substring(0, strNum.length - 1);
    lengthTracker--;
    return cascade(strNum)
  } else {
    return strNum;
  }
}

cascade(143)

this successfully outputs

'143'
'14'
'1'

How would I add the numbers back onto it one by one afterward?

Thank you for your time!
