convert milliseconds to seconds JS

function millisToMinutesAndSeconds(millis) {
  var minutes = Math.floor(millis / 60000);
  var seconds = ((millis % 60000) / 1000).toFixed(0);
  return minutes + ":" + (seconds < 10 ? '0' : '') + seconds;
}

millisToMinutesAndSeconds(298999); // "4:59"
millisToMinutesAndSeconds(60999);  // "1:01"

convert milliseconds to minutes and seconds javascript

const millisToMinutesAndSeconds = (millis) => {
    var minutes = Math.floor(millis / 60000);
    var seconds = ((millis % 60000) / 1000).toFixed(0);
	//ES6 interpolated literals/template literals 
  	//If seconds is less than 10 put a zero in front.
    return `${minutes}:${(seconds < 10 ? "0" : "")}${seconds}`;
}
    

how to convert milliseconds to time in javascript

const milliseconds = 1575909015000

const dateObject = new Date(milliseconds)

const humanDateFormat = dateObject.toLocaleString() //2019-12-9 10:30:15

dateObject.toLocaleString("en-US", {weekday: "long"}) // Monday
dateObject.toLocaleString("en-US", {month: "long"}) // December
dateObject.toLocaleString("en-US", {day: "numeric"}) // 9
dateObject.toLocaleString("en-US", {year: "numeric"}) // 2019
dateObject.toLocaleString("en-US", {hour: "numeric"}) // 10 AM
dateObject.toLocaleString("en-US", {minute: "numeric"}) // 30
dateObject.toLocaleString("en-US", {second: "numeric"}) // 15
dateObject.toLocaleString("en-US", {timeZoneName: "short"}) // 12/9/2019, 10:30:15 AM CST

convert milliseconds to time javascript

function msToTime(s) {

  // Pad to 2 or 3 digits, default is 2
  function pad(n, z) {
    z = z || 2;
    return ('00' + n).slice(-z);
  }

  var ms = s % 1000;
  s = (s - ms) / 1000;
  var secs = s % 60;
  s = (s - secs) / 60;
  var mins = s % 60;
  var hrs = (s - mins) / 60;

  return pad(hrs) + ':' + pad(mins) + ':' + pad(secs) + '.' + pad(ms, 3);
}

console.log(msToTime(55018))

function convertMsToHM(milliseconds) {
  let seconds = Math.floor(milliseconds / 1000);
  let minutes = Math.floor(seconds / 60);
  let hours = Math.floor(minutes / 60);
