What exactly is Node JS?
Node JS is a server-side platform based on the JavaScript Engine in Google Chrome. Ryan Dahl created Node JS in 2009, and the most recent version is v0.10.36. Node.js is a framework for quickly creating efficient and scalable network apps based on Chrome’s JavaScript engine. Furthermore, due to its non-blocking I/O architecture, Node JS is lightweight and practical, making it suitable for data-intensive authentic applications that run across numerous devices.
Node JS is an entirely free cross-platform runtime environment for generating server-side and networking applications. Node JS apps are written in JavaScript and run on OS X, Microsoft Windows, and even Linux using the Node JS runtime.
Node JS also comes with an extensive library of JavaScript modules, which significantly facilitates the creation of Node JS web applications.
Is it affordable to learn Node JS in 2021?
Although JavaScript is sweeping the IT employment market, many prospective software engineers are concerned that mastering the technology isn’t the best approach to obtaining their ideal job. However, they are justified in carefully examining their options, as certain business areas are dominated by other languages, such as Python in the case of data analytics. Keeping in mind that Node JS is pretty popular and that Node JS developers are highly in demand, we’d say that it’s good to learn Node JS in 2021. Because of those reasons above, project owners are looking to hire Node JS developers much more frequently than before.
Node JS is the most widely used framework on the planet
You’ll feel equally comfortable if you look at the shifting popularity of development languages throughout time. Languages like Javascript, Node JS, and Python are progressively rising in popularity, whereas PHP and C# are gradually losing favor. Finally, JavaScript comes in second place on the most sought’ programming languages list, behind only Python. Both of these languages are gaining ground on their rivals. And when it comes to the most popular frameworks, Node JS is at the top of the list.
Top Companies That Have Their Apps Built With Node JS
LinkedIn’s mobile app has been updated, with Node JS being used throughout the mobile database stack. They saw a significant increase in capacity. Netflix, and even PayPal, and a long list of other firms have chosen Node.js. Node.js could be the way to go if you want to work for a large, inventive, and profitable firm.
JavaScript Developers do not face a labor shortage
While JavaScript appears to be at the top of every popularity and customer-based programming language classification chart we’ve seen, it isn’t always first. In 2017, there were still more job openings for Java. Nonetheless, the number of job vacancies for Software engineers is decreasing, while those for JavaScript and Python professionals are increasing or holding stable. Even for developers who want to focus on the client-side, Node.js is frequently recommended as an excellent framework to master.
Job postings might give you a misleading sense of how much demand there is for Node.js engineers. Many job ads for SQL or Java developers, according to studies, also need the expertise of Javascript or even Python. Node.js is also in the top four of the best-paying developer jobs list (fourth place).
The three most in-demand programming talents are JavaScript, C, and, of course, Java, but only one of them is on the increase. Can you estimate which one of them is the one with increasing popularity? It is, after all, JavaScript.
When Should You Use Node.js?
The domains where Node.js is proven to be an excellent technological partner are as follows.
- Applications that are I/O bound
- Applications using streaming data
- Real-time Data-Intensive Applications
- Applications that are based on JSON APIs
- Applications that are barely one page long
We’d definitely not recommend using Node JS for some extra intensive CPU applications.
The Bottom Line
In 2021, investing in JavaScript and Node.js development abilities is still a wise decision. The language is required for web development, which is where much of the action these days takes place. Therefore finding intriguing employment opportunities for Node.js engineers isn’t tough. Unless you want to work in an old-school corporate environment, Node.js could be the best alternative. Primarily when used in conjunction with another popular framework like React or Vue.
