The popularity of JavaScript has resulted in many changes, and the face of web development today is very different. Things we can accomplish on the web now with JavaScript running on the server and in the browser were unthinkable just a few years ago or were encapsulated within sandboxed environments like Flash or Java Applets.

Node.js is a run-time environment for JavaScript that runs outside of a browser. In recent years, Node.js has demonstrated immense promise, which is why IT giants like Microsoft, Netflix, PayPal, Linked In, IBM, Walmart, and Yahoo employ it as their backend.

What is Node.js?

It is not a framework or a library, but as already said, Node.js is a run-time environment. Being introduced back in 2009 by Ryan Dahl, it was immediately recognised as “the most exciting single piece of software in the current JavaScript universe”.

Node.js was created with the concept of “JavaScript everywhere” in mind, allowing developers to create online applications using a single programming language. The Node.js package ecosystem “Node package manager (NPM)” is the world’s largest ecosystem of open source libraries, and developers use it to save time and code efficiently.

Architecture of Node.js

The mechanics of Node.js are what make it so popular among programmers. Unlike most run-time environments, which use multi-threaded processing models, Node.js does everything in a single thread.

A thread is chosen for each request when using multiple-thread processing until all of the threads are used up. When this happens, the server must wait for a now busy thread to become available again. A single-thread design can operate and scale faster and more efficiently than multiple-thread configurations. Single-thread architectures use event loops to conduct blocked Input/Output activities non-blocking, processing each request with a single main thread.

Why Learn Node.js?

Demand in MarketAside from Netflix, Node.js is widely used by global powerhouses such as Uber, PayPal, and LinkedIn. If these huge firms use it, it’s certainly a famous invention right now and something to keep in mind as you expand your employability range of abilities and make career selections. Hence, it is pretty evident that Node.js is a big deal in the tech community.

  • Microservices

Node.js is an excellent choice for microservices architecture because it is a lightweight technology tool. Microservices are a rapidly evolving design style that provides greater flexibility and adaptability than the traditional stone monolith. Regardless of whether you’ve worked with microservices before, studying Node.js is a good way to prepare yourself for a future in which they’ll become increasingly prevalent.

  • Easy to Learn

Nearly every front-end developer is familiar with Javascript, one of the most popular programming languages for front-end development. As a result, switching to Node.js for the backend is significantly easier for developers. Even for a junior Javascript coder, it takes less effort and time to learn and work with.

  • Active Community

The Node.js developers’ community is a strong and active group of developers who work to improve Node.js regularly. Thanks to the collaboration of JavaScript programmers and their contributions to the community, you have access to a wealth of ready-to-use solutions, Github-hosted code, and a plethora of other options. Although it is still in its early stages, the community is growing rapidly, and its members go above and beyond to supply others with best-in-class, dependable solutions.

  • Ideal for more than just Web development

Node.js being flexible, can be used for a variety of different purposes. The library’s community mainly develops online apps, but it’s also a handy tool for people in operations or infrastructure. This is because Node.js is an excellent tool for creating other development tools. Surprisingly, Node.js can be used in some Internet of Things (IoT) projects.
