About Node JS Tutorial
Welcome to this Node.js tutorial! In this tutorial, we'll explore the exciting world of Node.js—a runtime environment that allows you to build powerful server-side applications using JavaScript. Whether you're new to programming or an experienced developer, this tutorial will provide you with a solid foundation to start creating web servers, APIs, and more using Node.js.
What is Node.js?
Node.js is an open-source, cross-platform runtime environment built on the V8 JavaScript engine. It empowers you to use JavaScript on the server side, allowing you to handle network requests, perform file operations, manage databases, and build real-time applications efficiently. With its non-blocking, asynchronous architecture and event-driven nature, Node.js is designed for high concurrency and responsiveness.
