What is Node.js?
Node.js is an open-source, cross-platform JavaScript runtime built on Chrome's V8 engine. It allows developers to run JavaScript on the server side, making it ideal for building scalable, event-driven applications like web servers, APIs, and real-time applications.
Why Learn Node.js?
JavaScript Everywhere: Write both client-side and server-side code in JavaScript.
Non-Blocking I/O: Efficiently handle many concurrent requests with asynchronous, event-driven programming.
Scalability: Perfect for building high-performance, real-time applications.
Industry Standard: Node.js is widely used in backend development for web and mobile applications.
