    },
    showAlert:() => {
       alert("Hey I am alert");
       return wrapper(person);
    },
    sayGoodEvening:() => {
        console.log("Good Evening, " + person.name)
        return wrapper(person);
    },
    sayGoodNight:() => {
        console.log("Good Night, " + person.name)
        return wrapper(person);
    },
  });
  const person = {name:"StackOverflow"};
  const $ = (obj) => wrapper(obj);
  const $example = $(person);
  
  $example
    .showAlert()
    .sayGoodMorning()
    .sayGoodEvening()
    .sayGoodNight();
