Course Overview

Node.js is a powerful JavaScript runtime environment that enables developers to run server-side JavaScript code. It utilizes the V8 JavaScript engine from Google Chrome to execute code outside of a web browser. Node.js is renowned for its non-blocking, event-driven architecture, which allows for high concurrency and scalability, making it ideal for building fast and scalable network applications. With Node.js, developers can create a wide range of applications, including web servers, APIs, real-time chat applications, and more. Its extensive package ecosystem, facilitated by npm (Node Package Manager), provides access to a plethora of open-source libraries and tools, empowering developers to efficiently build and deploy feature-rich applications. Overall, Node.js revolutionizes server-side development by enabling JavaScript to be used across the entire web stack, fostering code reusability, and accelerating development cycles.
