Can you explain how inheritance works in JavaScript?

Look here's a simple example of how you can benefit from inheritance in JS

var Person = function(name){ 

    this.name = name;

};

var Student = undefined;

var Student = function(id, name){ 

    this.id = id;

    Person.call(this, name);

};

Student.prototype = Object.create(Person.prototype);

Student.prototype.constructor = Student;

var St1 = new Student('59gh14oq6', 'Inigo Montoya');
