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.
- Node.js is fast
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.
- 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.
- 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.
