Sum Hours:Minutes:Seconds in Java script

how can I sum hours:minutes:seconds in JavaScript. I mean by 04:32:05 03:14:03 To get 07:46:08

Ive tried

    var time1 = "01:00:01";
    var time2 = "01:00:10";
    var time3 = "01:54:00";
    var time4 = "01:30:00";
    var time5 = "01:00:00";
    var time6 = "01:00:00";
    var time7 = "01:00:00";
    
    var hour=0;
    var minute=0;
    var second=0;
    
    var splitTime1= time1.split(':');
    var splitTime2= time2.split(':');
    var splitTime3= time3.split(':');
    var splitTime4= time4.split(':');
    var splitTime5= time5.split(':');
    var splitTime6= time6.split(':');
    var splitTime7= time7.split(':');
    
    hour = parseInt(splitTime1[0]) + parseInt(splitTime2[0])  + parseInt(splitTime3[0])  + parseInt(splitTime4[0])  + parseInt(splitTime5[0])  + parseInt(splitTime6[0]) + parseInt(splitTime7[0]) 
    minute = parseInt(splitTime1[1]) + parseInt(splitTime2[1]) + parseInt(splitTime3[1]) + parseInt(splitTime4[1]) + parseInt(splitTime5[1]) + parseInt(splitTime6[1]) + parseInt(splitTime7[1])
    hour = hour + minute/60;
    minute = minute%60;
    second = parseInt(splitTime1[2]) + parseInt(splitTime2[2]) + parseInt(splitTime3[2]) 
    + parseInt(splitTime4[2]) + parseInt(splitTime5[2]) + parseInt(splitTime6[2]) + 
    parseInt(splitTime7[2]) 
    minute = minute + second/60;
    second = second%60;
    
   console.log(hour+ ":" + minute + ":"+ second)

The output I get is 8.4:24.183333333333334:11 instad of 08:24:11 any suggestions?

your making it very complex, you can reduce this by converting into Date objects and then add each date to get the sum of all dates Understanding Date and Time in JavaScript

The problem with your code is you are including the decimal point

hour = hour + minute/60;

you need to floor it.

hour = hour + Math.floor(minute/60);

Now how to do it without a lot of repetitive code.

function toSeconds(s) {
  const parts = s.split(':');
  return +parts[0] * 3600 + +parts[1] * 60 + +parts[2];
}

function secondsToHHMMSS(secs) {
  return Math.floor(secs / 3600).toString().padStart(2, '0') + ':' + 
         (Math.floor(secs / 60) % 60).toString().padStart(2, '0') + ':' + 
         (secs % 60).toString().padStart(2, '0');
}


const timestamps = ["01:00:01", "01:00:10", "01:54:00", "01:30:00", "01:00:00", "01:00:00", "01:00:00"];

const totalSeconds = timestamps.reduce(function(total, ts) {
  return total + toSeconds(ts); 
}, 0);

const result = secondsToHHMMSS(totalSeconds);

console.log(result);

If you want to sum of times then you should try this

var addTime = function (time1, time2) {
//   convert to ms
  var dateObject1 = new Date(time1).valueOf();
  var dateObject2 = new Date(time2).valueOf();
  
  return dateObject1 + dateObject2;
}


var time1 = new Date().setHours(4, 32, 5, 0);
var time2 = new Date().setHours(3, 14, 3, 0);

var sum = new Date(addTime(time1, time2));

var getFormatedTime = function (time) {
  return time.getHours()+':'+time.getMinutes()+':'+time.getSeconds()
}


console.log(getFormatedTime(sum))
