For even more than twenty full-fledged years, there was stateless-web which was based entirely on the request-response paradigm which was stateless as well. After almost a period of twenty years we have been introduced to web applications which have a two-way connection in real time. It is amazing and quite appreciable of Ryan Dahl to introduce something so unique and amazing to the world and improving our experience of using web applications to a whole new level. With the commencement of Node.js in web applications that too in real time, the technology of push notification has been employed and it has taken over web sockets, making things all the more easy and exciting. This is considered to be so revolutionary since after a long period of twenty years, the concept of two-way connection has come up in real-time due to which there can be initiation of communication from both ways. The client can initiate the communication or the server can also initiate the communication. This has made things much more easy and handy. The client and the server can also share data. They have full permission granted to exchange and share data freely.
There is a huge contrast which has come up since previously only the client had the permission to initiate communication but since the introduction of node.js, the communication has become two way, which means that it can be generated by both, either the client or the server. Also, it is based on open web stack which is HTML, CSS, and JS which usually run over the standard port 80. There are many arguments which come up stating that we have had such kind of things for many years in the form of Java Applets or Flash might be, but the actual truth and reality is that Flash and Java Applets were nothing more than sandboxed environments. They used the web which served as a transport protocol which they delivered to the clients. Also, all these ran in isolation. They were usually operated over ports which were non-standard and which might have required extra or additional permission for running it. After test most have coding platform features, Node.js was found to have numerous advantages and benefits and is now playing a key role in the technology stack which belongs to most of the famous and high profile companies. These high profile and extremely famous companies depend on the unique and superb benefits which node.js has to provide to its users. There is a foundation named as Node.js foundation which has put together in a consolidated form all the pros and cons and best thoughts as to why an enterprise should even consider Node.js in the form of a presentation which is quite effective and must be given a look through to understand all the major and minor functions which node.js has undertaken to fulfill and help his clients in the best possible way.
