Key features of Node.js

Node.js is a versatile runtime environment that lets you build server-side and networking applications using JavaScript. It works on OS X, Windows, and Linux.

With a vast library of JavaScript modules, Node.js simplifies web application development. It extends Node.js capabilities, enabling integration with APIs, other languages, and third-party libraries. It’s a key player in the ‘JavaScript everywhere’ approach for web app development, handling both server-side and client-side tasks.

Web development is a dynamic field that requires continuous innovation. JavaScript, widely preferred for front-end programming, has gained additional support from Node.js for back-end development. Node.js is now also utilized in mobile app development alongside its role in online development.

Key Features of Node.js

1. Asynchronous and Event-Driven: The Node.js library’s APIs are all asynchronous (non-blocking) in nature. A server built with Node.JS never waits for data from an API. from an API. After accessing an API, the server moves on to the next one. In order to receive and track responses of previous API requests, it uses a notification mechanism called Events.
2. Single-Threaded: Node.js employs a single-threaded architecture with event looping, making it very scalable. In contrast to typical servers, which create limited threads to process requests, the event mechanism allows the node.js server to reply in a non-blocking manner and makes it more scalable. When compared to traditional servers like Apache HTTP Server, Node.js uses a single-threaded program that can handle a considerably larger number of requests.
3. Scalable: NodeJs addresses one of the most pressing concerns in software development: scalability. Nowadays, most organizations demand scalable software. NodeJs can also handle concurrent requests efficiently. It has a cluster module that manages load balancing for all CPU cores that are active. The capability of NodeJs to partition applications horizontally is its most appealing feature. It achieves this through the use of child processes. This allows the organizations to provide distinct app versions to different target audiences, allowing them to cater to client preferences for customization.
4. Quick execution of code: Node.js makes use of the V8 JavaScript Runtime motor, which is also used by Google Chrome. Hub provides a wrapper for the JavaScript motor, which makes the runtime motor faster. As a result, the preparation of requests inside Node.js becomes faster as well.
5. Cross-platform compatibility: It works on different operating systems like OS X, Windows, and Linux.
6. Uses JavaScript: It supports the ‘JavaScript everywhere’ paradigm, enabling developers to use JavaScript for both server-side scripting and client-side programming.
7. Fast data streaming: When data is transmitted in multiple streams, processing them takes a long time. Node.js processes data at a very fast rate. It processes and uploads a file simultaneously, thereby saving a lot of time. As a result, NodeJs improves the overall speed of data and video streaming.
8. No Buffering: In a Node.js application, data is never buffered.
9. Large Module Library: Node.js comes with a vast library of pre-built JavaScript modules, making it easier to develop web applications.
10. Back-End Development: Node.js is particularly useful for back-end development, complementing JavaScript’s role in front-end programming.
11. Real-Time Applications: It’s well-suited for real-time applications, such as chat applications and online gaming, due to its event-driven architecture.
12. Community Support: It has a vibrant and active community, providing ample resources, modules, and support for developers.
