Write a function, which takes a non-negative integer (seconds) as input and returns the time in a human-readable format (HH:MM:SS) HH = hours, padded to 2 digits, range: 00 - 99 MM = minutes, padded to 2 digits, range: 00 - 59 SS = seconds, padded to 2 digits, range: 00 - 59 The maximum time never exceeds 359999 (99:59:59)

humanReadDate.js

function humanReadable(seconds) {
  var hours = seconds / 3600, minutes = seconds / 60 % 60, newSeconds = seconds %  60 ;
  return formatDate(hours) +':' + formatDate(minutes)+':'+formatDate(newSeconds)
}

function formatDate(n){
  var number = Number.parseInt(n)
  return number > 9? number : '0'+number;
}
