In this tutorial, let’s see how to convert seconds to Hours Minutes Seconds (HH-MM-SS) format in JavaScript.

An easy way is to create a date will null value, set seconds to it, read date as string.

let timeInSecs = 5000;
let date= new Date(null);
date.setSeconds(timeInSecs); 
let hhmmsstime = date.toISOString().substr(11, 8);
console.log(hhmmsstime); //01:23:20
