構造函數的使用

var aF = function() {
    console.log("aF");
  };
  var bF = function() {
    console.log("bF");
  };
  function numb(a, FunStart, b, FunEnd) {
    a++;
    b++;
    console.log(a);
    console.log(b);
    FunStart();
    FunEnd();
  }

  function Person() {
    this.xingming = function() {
      var mingzi = "aa";
      console.log(mingzi);
      numb(10, aF, 20, bF);
    };
    this.nianling = function() {
      var suishu = 29;
      console.log(suishu);
    };
  }
  var people = new Person();

  setTimeout(() => {
    people.xingming();
  }, 2000);
