Event-driven programming is used to synchronize the occurrence of multiple events and to make the program as simple as possible. The basic components of an Event-Driven Program are: A callback function ( called an event handler) is called when an event is triggered.
How is Event-Driven Programming implemented in NodeJS?
Event-Driven Programming makes use of the following concepts: An Event Handler is a callback function that will be called when an event is triggered. A Main Loop listens for event triggers and calls the associated event handler for that event.
What is event-driven programming explain with example?
