对象数组相对于另一个数组进行过滤！

    let userList = [
      {
        name: "wangzz",
        code: '001',
        age: 24
      },
      {
        name: "wangxx",
        code: "002",
        age: 25

      },
      {
        name: "wangdd",
        code: "003",
        age: 26
      },
      {
        name: "wangii",
        code: "004",
        age: 27
      },
      {
        name: "wangqq",
        code: "005",
        age: 28
      }

    ]

    let saveCode = ["001", "002", "005"]

    let res = userList.filter(item =>
      saveCode.includes(item.code)
    )
    console.log(res)
