Ever heard of Node.js ? Well, if not then here is what this is. Node.js is an open source, cross-platform runtime environment for networking and server-side applications. Node.js applications are usually written in Javascript. They can also be used or run within the Node.js runtime on Microsoft Windows, OS X, FreeBSD, Linux, IBM I and NonStop.

Node.js applications give an event-driven architecture and a non-blocking I/O API that optimizes an application’s scalability. In most cases, this technology is commonly used for real time web applications.

Reasons why you should use Node.js

There are certainly more than enough reasons why you should use Node.js irrespective of your experience level.

  1. You already know Javascript

You definitely must be already familiar with Javascript, right? Using this app not only does it help you gain more mental energy but also you will practically gain as well. The re-using of your templates and models you definitely reduce your application’s size which in turn reduces the complexity as well as chances for bugs. On the other hand, Javascript is also here to stay; it is not going anywhere anytime soon.

  1. Node.js is fast

Node.js uses the V8 engine which is developed by Google for use in Chrome. In addition, V8 is known to compile and execute Javascript at a very high speed thanks to the fact that it compiles Javascript into a native machine code.

Additionally, the event loop is yet another magic of using Node.js. The event loop, on the other hand, is a single thread which performs all I/O operations asynchronously. Usually, I/O operations mostly run synchronously which in most cases uses a lot of memory and is quite difficult to program.

In other words, reading/writing to the database, reading and writing to network connections,  and reading/writing to the file-system, all of which are very common tasks in websites apps executes very fast with Node.js. That is, Node.js allows one to build scalable network applications which are fast; the applications are capable of handling a big number of simultaneous connections.

  1. Real-time made easy

Node.js is well known as a multi-user and real-time web application such as games and chats. The multi-user requirement is taken care by the Node.js’ event loop. The websocket, on the other hand, enables the real-time power. The websocket is a two-way communication channel between the server and client. This makes it possible for the server to send data to the client as easily as possible.

  1. Streaming data

For a long time, web frameworks treat HTTP responses and requests as whole data objects. They are I/O streams, something evident if you stream a file from the file-system. But you can now use Node.js to come up, create of build some really cool things. That is for the reason that Node.js can read/write streams to websockets the same way it can to HTTP.

As seen above, there are many reasons, beyond any reasonable doubt, why you ought to really consider using Node.js. Try it today and you will love it.
