What would be the output? (Different ways of Prototype calls)

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

Person.prototype.sayName = function () {
  console.log(this.name);
}

var yomesh = new Person('yomesh');

console.log(yomesh.sayName());
console.log(Person.prototype.sayName());
console.log(Object.getPrototypeOf(yomesh).sayName());
console.log(yomesh.__proto__.sayName());
