格式化時間 戳

小白看到微信小程式的一個格式化時間戳，挺好用的，記錄一下

// 格式化日期時間
const formatTime = date => {
  const data = new Date(date);
  const year = data.getFullYear()
  const month = data.getMonth() + 1
  const day = data.getDate()
  const hour = data.getHours()
  const minute = data.getMinutes()
  const second = data.getSeconds()

  return [year, month, day].map(formatNumber).join('/') + ' ' + [hour, minute, second].map(formatNumber).join(':')
}
// 格式化日期
const formatDate = date => {
  const data = new Date(date);
  const year = data.getFullYear()
  const month = data.getMonth() + 1
  const day = data.getDate()
  const hour = data.getHours()
  const minute = data.getMinutes()
  const second = data.getSeconds()

  return [year, month, day].map(formatNumber).join('-') 
}
// 在單數字前面加0
const formatNumber = n => {
  n = n.toString()
  return n[1] ? n : '0' + n
}

module.exports = {
  formatTime: formatTime,
  formatDate,
}
