What am I doing wrong with this prototype setup?

See the simplified code. What am I not getting with this pattern?

    var john = new person('john');
    john.hi();

    function person(name) {
      this.name = name;
    }

    person.prototype.hi = function() {
      console.log('hi there. Name is ' + this.name);
    };

You could also add prototype function after the creation of your object, and this function can be called by all the instances, even those created before. Because when you call a function, the prototype chain will be searched if no function is found on your object itself.

If there's anything wrong it is the order of things. Other than that this seems correct.

function person(name) {
  this.name = name;
}

person.prototype.hi = function() {
  console.log('hi there. Name is ' + this.name);
};

var john = new person('john');
john.hi();
