js将毫秒秒数转换为00:00:00格式

const formatTime = (millisecond)=>{
    let seconds = Math.round(millisecond / 1000);
    let result = [];
    let count = 2;
    while(count >= 0) {
        let current = Math.floor(seconds / (60 ** count));
        result.push(current);
        seconds -= current * (60 ** count);
        --count;
    }
    return result.map(item => item <= 9 ? `0${item}` : item).join(":")
}
