There has been a constant rise in the popularity of JavaScript, which has brought along numerous changes. These changes have helped in changing the face of web development in today’s world tremendously and have given a new meaning to it as well. In the past or previous years when we had no access to the internet, there were a lot of things which we could not have even imagined doing which we are capable of doing today with the help of internet. We can do numerous things on the internet or the web today. We can access the internet today on our laptops or desktops along with the JavaScript running in the browser as well as the server. Even imagining such a today a few years back seemed impossible. We were packed within many sandboxed environments such as Java Applets or Flash might be back then.
The world has seen huge progress in the field of technology in recent times as compared to the times which existed several few years back. There are huge benefits of JavaScript which one must necessarily be aware of as it will help in making our understanding of Node JS even more enhanced and better. JavaScript helps in unifying and bringing together the language and format of the data (JSON) across the stack. It also gives you permission to reuse the developer resources in the best possible way according to your requirements. This is a major advantage and usage of JavaScript which will benefit you while you incorporate or use Node in your stack.
Node.js is basically a compiled package of Google’s V8 JavaScript engine. It also a packaged version of a core library and the libuv platform abstraction layer, which has been written in the JavaScript primarily. Ryan Dahl is the person who created Node.js and is known as the creator of Node.js. His major aim or motive was to create websites which contained push capability in real-time. He had drawn his inspiration from popular applications such as Gmail. In Node.js, he gave the developers a tool, using which they could work in the non-blocking, event-driven I/O paradigm. He tried to develop something which was greatly inspired by the Gmail application and gave the developers an excellent tool to use and work with as well. He is very popular for the contributions which he has made in the field of technology through the creation of Node.js. He has made things quite simple and sorted as well with the introduction of Node.js to the world.
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.
Node.js has the primary function and usage of being used for non-blocking and for servers which are event-driven since it is single-threaded in nature. It has also seen usage in websites which are traditional and also used in various backend API services. It was actually designed with keeping in mind the push-based architectures which could be used in real time. It is basically a server environment which is open source in nature and uses JavaScript. Also, a person who wants to become a node.js developer should have great knowledge of all the concepts of node.js and he should also be capable of writing and implementing all the codes which are of reusable and testable in nature.
