What Is Node JS?

Node JS is a server-side platform that is built on Google Chrome's JavaScript Engine (V8 Engine). The Node JS library was developed by Ryan Dahl in 2009 and its current version as of the time of this writing is v 13.0.1.

Node.js is a javascript library that is built on Google Chrome's JavaScript runtime engine to enable software developers to easily build very fast and scalable network applications. Node.js makes use of an event-driven, non-blocking Input-Output model that makes it lightweight, very effective and perfect for real-time web applications that highly depend on data that run across multiple devices.

Node.js is an Open-Source, multi-platform development environment that is used for developing server-side and Networking Applications. Node.js applications are generally written in JavaScript and they can be run inside the Node.js runtime on Microsoft Windows, OS X and the flavors of Linux.

The Node.js library also offers a rich set of various JavaScript Libraries and Modules that makes easy, the process of developing easily scalable web applications using Node.js to a great extent.

Features Of Node JS

Node JS has so many features and characteristics. The following are some of the important features that make Node.js to become the first choice of software developers.

1. Asynchronous and Event-Driven: All APIs found in the Node.js library are asynchronous, which means that they are non-blocking. It basically means that a web server that is based or built upon Node JS does not wait for an API to return request data. The server goes straight to the next API after requesting the API resource and a notification tool of Events in Node.js helps the webserver to get a response from the API that was called previously.

2. Very Fast: Node JS library, Being built on Google Chrome's V8 JavaScript Engine, is very fast in executing the code that is being run on it.

3. Single-Threaded but Highly Scalable: Node.js makes use of a single-threaded model that includes looping of events. The event mechanism of Node JS helps the server to respond in a non-blocking way and it makes the server highly scalable which is opposing to traditional web servers that use the threading feature to create limited threads that handle requests. Node.js web servers use a single-threaded program and the same single-threaded program can provide better function and service to a much larger number of requests than conventional web servers like the Apache HTTP Server. 

4. No Buffering: Node.js applications does not buffer any data. Its applications simply output the data in pieces. 

5. License: The Node JS library is released under the MIT license. 

Why Study Node JS

Any computer programming language will give you some reasons to prefer them over the others. The thing about Node.js is that it was designed and developed with the sole purpose of managing applications at scale. Modern tooling and its embrace of the more presumptuous-looking way of building complex web applications make Node.js stand out from other computer programming technologies.

With over a billion downloads, Node.js shines in developing real-time software applications, internet of things applications, and several microservice applications. It is gaining traction faster than any other software technology and it ranks in the top most in-demand software developer skills.

Below are some of the reasons why you should study Node JS: 

1. Performance and Scalability: Node.js is built on top the Google Chrome’s V8 runtime engine, it is developed with C++, designed for several software operating systems and it is extremely fast. Both chrome V8 and Node are updated frequently, with several optimizations for performance, security patches, and its support for modern JavaScript features. The use of JavaScript also signifies that converting JSON data which is the most common data interchange format on the Web is fast by default.

2. Data Streaming: In more conventional web platforms, HTTP requests and responses are being treated as an isolated event; in fact, they actually stream of data. This observation can be employed in Node JS to develop some cool features. For example, it is very possible to process files while they’re still being uploaded to the server, as the data comes into the server through a stream and we can process it in an online manner. This could be carried out for real-time encoding of audio or video files.

3. Proxy: Node.js is easily used as a server-side proxy where it can manage a large number of concurrent and simultaneous connections in a manner that is non-blocking. It’s particularly useful for proxying various services with different response times or gathering data from several source points.

4. Queed Inputs: If you’re getting a high amount of simultaneous and concurrent data, your database can become a bottleneck. Node.js can easily manage the concurrent connections themselves.

Career Opportunities in Node JS

At the entry/ beginner level, most people start their career as a front-end developer who develops software applications using HTML, CSS, and JavaScript. Then to make things more convenient, and powerful, additional technologies need to be included in the project and Node JS is one such technology.

After spending a few years as a developer with this technology candidates are normally promoted as a team leader, architect, scrum master and product owner. Those who prefer to move towards the management-based roles usually become team manager, people manager, or line manager.

Many developers also have the option to own their businesses or start-ups. Such as web development consulting, online and classroom-based tutorials, book writing and teaching. Game development, app development and product development can also be an exciting career option for Node.js professionals and freelancers.
