How Node JS event loop works

Node JS Web Server internally maintains a Limited Thread pool to provide services to the Client Requests . Node JS Web Server receives those requests and places them into a Queue. It is known as “Event Queue”. Node JS Web Server internally has a Component, known as “Event Loop”.

Node. js is primarily used for non-blocking, event-driven servers , due to its single-threaded nature. It’s used for traditional web sites and back-end API services, but was designed with real-time, push-based architectures in mind.

Node. js is not a programming language . Rather, it’s a runtime environment that’s used to run JavaScript outside the browser.
