js简易uid生成

function myId () {
  const time = new Date().getTime().toString()
  const timeArr = time.split('')
  const arr = 'abcdefghijklmnopqrstuvwxyz'.split('')
  timeArr.forEach((item, index) => {
    const random = arr[Math.floor(Math.random() * arr.length)]
    timeArr.splice(index * 2, 0, random)
  })
  return timeArr.join('')
}

取得字符串类似这样子： "c1n6m2v3v0e5c1v9a5s8g5h3p0"

应该不会重复吧 嘿嘿
