What does one need to build a website or a mobile application? A programming language. What else? An ‘environment’ or a set of processes and programming tools used to create the program. That brings us to Node.js. Node is a popular environment that is used by giants of the IT world such as PayPal, Walmart, and Netflix among others.
The what, how, and why of Node.JS
What exactly is Node.JS?
Node is open-source, which means it is free to use, modify, and distribute. It is cross-platform, which is again kind of good news, as it means that node is a platform-independent software that can be implemented on multiple computing platforms, thus giving it flexibility.
Node.JS is best effective when it comes to dynamic and interactive applications, such as a messenger, that has a continuous data flow.
How it works
One may argue that all of the things written above can be done without Node.js being absolutely necessary, then why go for Node.js? For the following reasons:
This is the greatest reason most of the Fortune 500 tech companies are switching to Node.js. There are proven stats that show that building dynamic websites or applications take considerably lesser time and man-hours using Node.js. The code required is also shorter, with many companies claiming they replaced an existing code by a 30-40% shorter one, thanks to Node. Along with being fast, it is also highly scalable. In a data-driven world, that is a very important feature.
- Single threaded architecture
Unlike other platforms that create a new thread for every request, Node uses a single threaded architecture that reduces the RAM usage. It uses a non-blocking input output mechanism, where multiple requests can be handled in the event loop without extra threads.
In simple terms, it can be used for Windows, Linux, or Mac, and you do not need the particular platform to build for the specific platform.
What it means for me
It means interesting opportunities in the ever-expanding field of web and app development. The community for Node.JS is constantly growing and new improvements are happening every day with a large number of people constantly working on it. All the great IT companies have understood the importance of Node.JS. Now that you know what Node.JS is about, the next step is to enroll in a good Node JS course with hands-on Web Development training!
