Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine. It allows you to build fast and scalable network applications by using an event-driven, non-blocking I/O model.
What is node.js?
Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine and libuv, which provides asynchronous I/O operations to Node.js applications. The core library allows you to build scalable network applications quickly without sacrificing the full power of the language.
Node has been designed from the ground up for speed and efficiency: instead of blocking execution when waiting for I/O, it uses an event-driven model that allows your code to continue running (and responding) while it waits for results from external processes like databases or external systems like WebSockets, HTTP requests, etc.

The node.js package ecosystem is the largest ecosystem of open-source libraries in the world
Node.js is the most popular server-side framework used today, and it’s not hard to see why. The node.js package ecosystem is the largest ecosystem of open-source libraries in the world.
In addition to being used by companies like Netflix and Uber, node has also been adopted by many popular websites like GitHub and PayPal as well as massive corporations such as Walmart and Apple.

A fast and scalable networking platform for creating server-side apps
Node.js is a fast, scalable networking platform built on Chrome’s V8 JavaScript runtime for the browser. It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient.
Node.js uses an HTTP library to communicate with different web servers, databases and other services that run on the same machine as your application code (or elsewhere). The library provides all the features required by modern web applications: request handling, response parsing etc., making your life easier when working with data in various formats—JSON/XML/CSV; JSONP; PUT/POST requests; cookies etc..

Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine
Node.js is a runtime, or virtual machine, for JavaScript. It’s built on Google’s V8 JavaScript engine and runs on Linux, OS X, and Windows machines.
Node.js is designed to be lightweight and fast—it can run in the background just like other programs such as Apache Web Server or IIS (Internet Information Services).

Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient
Node.js is a server-side JavaScript runtime that allows you to build fast and scalable web applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient.
Node’s core library provides APIs for building network applications quickly and easily with minimal code by leveraging the low overhead of asynchronous programming techniques like callbacks or promise objects instead of blocking synchronous code loops (e.g., reading from a file until it ends).

Good at processing a large number of simultaneous connections with high throughput and low latency
Node.js is a good choice for processing a large number of simultaneous connections with high throughput and low latency. It’s fast, and it scales well in large numbers of servers thanks to its non-blocking architecture.
Node.js was created by Ryan Dahl, who wrote it during his time at Google in 2009 as an experiment in building rich internet applications without the use of traditional servers or virtual machines (VMs). The open source project has since been adopted by thousands of companies around the world who use it to build web apps that handle millions of requests per second on mobile devices or IoT devices like wearables or sensors embedded in industrial equipment such as jet engines (to name two examples).
There are many good reasons to learn more about node.js
Node.js is a great way to learn JavaScript, but that’s not all it can do. It’s also perfect for learning event-driven programming, asynchronous I/O, and more!
Node.js is an open-source project that enables developers to build real-time web applications using JavaScript by providing them with the tools they need to write scalable, fast, and energy-efficient code.
