We’ll look at what it is, why it’s important, and how you can use it to your benefit.
What Is Node.js?
The asynchronous behavior of Node.js is accomplished by event callbacks, which are established with the use of functions, data structures called event emitter, and the scheduling of an internal timer loop. The event emitter allows data to pass between the caller and callee in real-time like events; timers and listeners are established to handle data in a later time. An event loop is designed to run each queued timer callback in turn, using non-blocking I/O operations that launch when no callbacks are pending.
