Person adam = new Person();
In JavaScript you would do:
var adam = new Person();

Person were a class, but it’s important to keep in mind that Person is still just a function.
Principle
When it comes to adopting an inheritance pattern for your project, you have quite a few options. You should always strive for picking a modern pattern, unless the team is really uncomfortable if there are no classes involved.
