const formatTime = date => {

const year = date.getFullYear()

const month = date.getMonth() +

const day = date.getDate()

const hour = date.getHours()

const minute = date.getMinutes()

const second = date.getSeconds()

return [year, month, day].map(formatNumber).join('-') + ' ' + [hour, minute, second].map(formatNumber).join(':'

const formatNumber = n => {

n = n.toString()

return n[] ? n : '0' + n

module.exports = {

formatTime: formatTime

}

关于module的文档，没有说明上述用法。上述用法和文档描述的不同，我不知道什么区别
