What is an EventEmitter?
The EventEmitter class is a built-in class that resides in the events module of Node.js
Creating EventEmitters
We will create an EventEmitter. This can be done either via creating an instance of the class itself, or by implementing it through a custom class and then creating an instance of that class.
Creating an EventEmitter Object
We will create simple event-emitting object that will emit an event that contains information about the application's uptime, every second.
