Javascript vs Coffeescript

CoffeeScript

class Person
   @name: null
   @age: 18


   constructor: (@name, @age) ->
     if @name == 'Hello'
         $(".name").html "Yeah, you made it!"
     if @age > 18
         $(".age").html "Welcome home!@"

   setAge(@age) ->

   setName(@name) ->

   getAge() ->
      @age

   getName() ->
      @name

Javascript

var Person;

Person = (function() {

  Person.name = null;

  Person.age = 18;

  function Person(name, age) {
    this.name = name;
    this.age = age;
    if (this.name === 'Hello') {
      $(".name").html("Yeah, you made it!");
    }
    if (this.age > 18) {
      $(".age").html("Welcome home!@");
    }
  }

  setAge(Person.age)(function() {});

  setName(Person.name)(function() {});

  getAge()(function() {
    return this.age;
  });

  getName()(function() {
    return this.name;
  });

  return Person;

})();
