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.
- 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.
- 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.
- 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.
