Daily Coding Challenge - Duration Formatter

JavaScript

Tell us what’s happening:

The coding challenge for today has a bug
The instructions clearly state that “Minutes: Should omit leading zeros when they aren’t needed. Use “0” if the duration is less than one minute.” but the second test requires a leading zero at the minutes section of the output which by the instructions, it is supposed to be “1:6:40”
This bug makes it difficult to complete the challenge
I don’t know if anyone else faces the same problem but I’ll be grateful if this bug is fixed as soon as possible

Your code so far

function format(seconds) {
  let minutes = Number.parseInt(seconds/60);
  const hours = Number.parseInt(minutes/60);
  seconds%=60;
  if(seconds<10){
    seconds=`0${seconds}`;
  }
  minutes%=60;
  if(minutes<10){
    minutes=`0${minutes}`
  }

  if(hours){
    return `${hours}:${minutes}:${seconds}`
  }else{
    return `${minutes}:${seconds}`
  }
}

it is needed there, there are also hours. It is not needed for when you have only minutes, not hours, like 8:20 instead of 08:20

by the instructions, if it was an hour and 8 minutes, then you need a leading 0 for minutes, 1:08:20, but see how you do not have the leading 0 for hours?

Okay, thanks so much for the clarification.
