What is Node.JS ?
Node.js is becoming the first choice development frameworks for software architects due to some of these compelling features:
Asynchronous and Event Driven
All APIs of Node.js library are asynchronous that is, non-blocking. It essentially means a Node.js based server never waits for an API to return data. The server moves to the next API after calling it and a notification mechanism of Events of Node.js helps the server to get a response from the previous API call.
Single Threaded but Highly Scalable
Node.js uses a single threaded model with event looping. Event mechanism helps the server to respond in a non-blocking way and makes the server highly scalable as opposed to traditional servers which create limited threads to handle requests. Node.js uses a single threaded program and the same program can provide service to a much larger number of requests than traditional servers like Apache HTTP Server.
Node.js applications never buffer any data. These applications simply output the data in chunks.
