I have got to add

Answer 1

For add array of time-format strings (including seconds and without counting days).

For example:

Input: times = ['00:00:10', '00:24:00']

Output 00:24:10

// Add two times in hh:mm:ss format
function addTimes(times = []) {

    const z = (n) => (n < 10 ? '0' : '') + n;

    let hour = 0
    let minute = 0
    let second = 0
    for (const time of times) {
        const splited = time.split(':');
        hour += parseInt(splited[0]);
        minute += parseInt(splited[1])
        second += parseInt(splited[2])
    }
    const seconds = second % 60
    const minutes = parseInt(minute % 60) + parseInt(second / 60)
    const hours = hour + parseInt(minute / 60)

    return z(hours) + ':' + z(minutes) + ':' + z(seconds)
}
