Node.js: the new-age player in the tech-mart

One might have got tangled in the loop of start servers and end servers and got their eyes tired of the merciless screen timings by hustling to code the very typical block call like, "EventMachine::run()."

The open-source, cross-platform and back-end JavaScript runtime environment of Node.js aims to make the coding life easier by eradicating such a start-the-event-loop call. An American software engineer, Ryan Dhal, created a non-language, non-database development tool-- Node.js, in 2009 on Chrome's JavaScript to facilitate the production of fast and scalable network applications.

The tool runs in a single process without creating new threads simultaneously for every new request. This process enables the application to read and process a thousand requests simultaneously within a single server, lessening the burden of managing thread conjunctions, which is the main cause behind bugs.?

It has rendered the applications created with Node.js to be highly scalable, thus, making the user's life free of tiresome workload and transactions.

This 21st-century high-tech tool also provides a set of asynchronous (non-blocking) I/O primitives in the standard library to avoid the blocking of JavaScript codes. These standard libraries are registered using non-blocking paradigms making the tendency of blocking a rare case scenario and not a norm found in any other application.

While performing an I/O operation, such as accessing a database or reading from the network, Node.js resumes the operation when the response is reverted, instead of blocking the thread and wasting time on high CPU usage cycles.

Another salient feature that makes more than half of the application developers use Node.js is that it does not necessitate the need to learn an entirely new language. The application developers who write JavaScript for the browsers use Node.js as they can write the server-side codes in addition to the client-side codes with their pre-requisite knowledge.

With a user base of one of the most prominent websites such as LinkedIn, GoDaddy, Netflix and so many more, Node.js has been ranked as the sixth most popular technology tool, according to StackOverflow's 2021 Developer Survey.?
