Event Driven Applications
## Event Driven Programming:
- In computer programming, event-driven programming is a programming paradigm in which the flow of the program is determined by events such as user actions, sensor outputs, or messages from other programs or threads.
- In web development Event-driven programming is the dominant paradigm used in graphical user interfaces and other applications (e.g., JavaScript web applications) that are centered on performing certain actions in response to user input.
## EventEmitter:
- EventEmitter Allows us to make events in node.js.
- Many objects in a Node emit events, for example, a net.Server emits an event each time a peer connects to it, an fs.readStream emits an event when the file is opened. All objects which emit events are the instances of events.EventEmitter.
- We access the EventEmitter class through the events module.
## Removing Listeners:
- We can use the
removeListenerorremoveAllListenersmethod.
