Introduction to Node JS

Introduction to Node JS

Node JS has transformed the landscape of web development by facilitating the execution of JavaScript on the server side. It is a cross-platform, open-source runtime environment constructed on Chrome’s V8 JavaScript engine. 

By virtue of its event-driven, non-blocking architecture, Node JS presents a distinctive methodology for constructing applications that are both scalable and high-performing.

At its core, Node JS allows developers to write JS code that runs on the server side, providing a seamless transition from front-end to back-end development. It eliminates the need for separate server-side languages, reducing the complexity of web application development. Whether you’re building web servers, APIs, real-time applications, or microservices, Node JS empowers developers to create robust and efficient solutions.
