# JavaScript Design Pattern

## Prototype Inheritance
function __extends(Child, Parent) {
    Child.prototype = new Parent();
}

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

function Student(name, studentId) {
    Person.call(this, name)
    this.studentId = studentId;
}

__extends(Student, Person);
