WHAT IS NODE.JS USED FOR?
It's perfect for real-time, data-intensive applications. It can be used as a backend engine, and it is also widely used in application interface (API) development. Since the de facto standard for REST APIs is JSON, real examples could be the use of Node.js in Netflix for things such as A/B scaling tests, the transition of the LinkedIn mobile backend application from Ruby on Rails to Node.js as well as in many other projects in different industries.
Node.js is multi-purpose, but shines with real time and high concurrency web applications (like social networks, mailers, and others) or real time communication like chats, or online games.
Job searches for Node.js developers have increased in recent years, as it is a widely used and required tool by companies, due to the fact that more and more information is handled in the applications and requirements for single-page applications, fast processing and non-blocking models are requested. In the competitive environment, companies try to attract their customers to the devices they use most to gain advantages over their competitors, and many technologies for mobile devices, such as React, Angular, Ionic, React Native, are based on Node.js.
The range of applications that a Node.js expert can create is large: web applications, command line applications, scripts for system administrators, network applications, and the list could go on. The speed of development is one of the advantages of this tool.
THE POPULARITY OF NODE.JS
As Node.js is focused on real time and data intensive applications, it is a high-demand tool that generated a big community, plus a lot of open source packages, many tools and support from different vendors. All this is generating a good environment for Node.js as it is proving to be a good technology, in terms of performance, to generate backend applications. Giants like LinkedIn, Netflix, PayPal, Uber, and Ebay, among others, display results of the use of Node.js in their environments and the results have been really good.
Node.js has become one of the most widely used tools for creating applications in the cloud, and is used massively in environments such as Amazon Web Services, for example.
