Answer 1

In case i understand you correctly and you have an array of eplapsedTime as text, You can run over the values and sum the hours in left part and minutes in right with split.

 const flightTimes = ['09:12','12:13','02:55','23:40','05:59']; let hours = 0, minutes = 0; flightTimes.forEach((time) => { const split = time.split(':'); hours += parseInt(split[0]); minutes += parseInt(split[1]); }); const formattedNumber = (num) => ("0" + num).slice(-2); hours += Math.floor(minutes/60); minutes = minutes % 60; console.log(formattedNumber(hours) + ':' + formattedNumber(minutes));
