event driven programming in node js
Whenever the Node server starts it. Event-driven programming is used to synchronize the occurrence of multiple events and to make the program as simple as possible.
Data property thats a record so a complex object.
. In this article we are going to discuss the concept of event driven programming in Node JS. EDP is very imperative when it comes to todays. Event-Driven Programming is a logical pattern that we can choose to confine our programming within to avoid issues of complexity and collision.
It means as soon as Node starts its server it simply initiates its variables declares functions and then simply waits for event to occur. Nodejs has multiple in-built events available through events module and EventEmitter class which are used to bind events and event-listeners as follows. Nodejs uses event driven programming.
