//1.数组
const arr = [2, 'uname', true]
console.log(arr)
console.table(arr)
console.log(arr[0], arr[1], arr[2])
console.log(typeof arr)
console.log(Array.isArray(arr))
//2.对象
const user = {
  id: 2,
  uname: '灭绝老师',
  IsMarried: true,
  emaill: 'admin@qq.com',
}
console.log(user.id, user.uname, user.IsMarried, user.emaill)
user1 = {
  id: 2,
  uname: '灭绝老师',
  show: function () {
    return `id=${this.id},uname=${this.uname}`
  },
}
console.log(user1.show())
