convert seconds to hours minutes and seconds and then to present time javascript code example

Example 1: javascript convert seconds to minutes seconds

function convertHMS(value) {
    const sec = parseInt(value, 10); // convert value to number if it's string
    let hours   = Math.floor(sec / 3600); // get hours
    let minutes = Math.floor((sec - (hours * 3600)) / 60); // get minutes
    let seconds = sec - (hours * 3600) - (minutes * 60); //  get seconds
    // add 0 if value < 10; Example: 2 => 02
    if (hours   < 10) {hours   = "0"+hours;}
    if (minutes < 10) {minutes = "0"+minutes;}
    if (seconds < 10) {seconds = "0"+seconds;}
    return hours+':'+minutes+':'+seconds; // Return is HH : MM : SS
}

Example 2: convert seconds to minutes javascript

// just added 2 formats in Glorious Guanaco code
function secondsToHms(value) {
    const sec = parseInt(value, 10); 
    let hours = Math.floor(sec / 3600); 
    let minutes = Math.floor((sec - hours * 3600) / 60); 
    let seconds = sec - hours * 3600 - minutes * 60;
    if (hours < 10) {      hours = '0' + hours;    }
    if (minutes < 10) {      minutes = '0' + minutes;    }
    if (seconds < 10) {      seconds = '0' + seconds;    }
    if (hours == 0) {
      return +minutes + ':' + seconds; // Return in MM:SS format
    } else {
      return hours + ':' + minutes + ':' + seconds; // Return in HH:MM:SS format
    }
  }
