The Importance of Node.Js Technology in Web Development

Node.js solves the issue with server-side JavaScript. JavaScript is a programming language that makes websites interactive by incorporating animations and effects. You can execute JavaScript on the server side with Nodejs, an open-source, cross-platform runtime environment. It is based on Chrome's V8 JavaScript engine and is intended to create scalable networks and event-driven apps. Node.js is commonly used to develop APIs, real-time web applications, and server-side applications.

Originally, JavaScript was a client-side scripting language that interacted with the backend. You had to insert the JavaScript code in the HTML document between the tags for it to execute. Nodejs allows JavaScript to be used on the server side, allowing developers to write backend code in the same language as they do for front-end development. This simplifies the development process and supports more efficient coding practices. This issue gave rise to a separate runtime environment for JavaScript. It should be possible for this runtime environment to support multiple connections at once and provide web apps with acceleration.
