Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

The logic is shielded from the global scope by a function wrapper (usually self-invoking) which returns an object representing the module's public interface. By immediately i
var statement is always necessary. Note that the import will create the module if it does not already exist

We wish to call the method A.getA, but with the special this object being the object c. If it were not for C have the spoiler method C.getA, we could write c.getA() to call A.getA with this being c. But the spoiler is there, so we have to do something else.
JavaScript has apply and call methods precisely for dealing with this problem. They allow us to specify the object that is to be bound to this during the method call. More exactly (and this has to be fully understoo
