Gain insights into what Node.js is and its fundamental characteristics:

• JavaScript Runtime: Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine, allowing developers to run JavaScript code outside the browser environment. This enables server-side scripting and the development of non-blocking, event-driven applications.
• Asynchronous I/O: Node.js utilizes an event-driven, non-blocking I/O model, which allows it to handle multiple concurrent connections efficiently. This makes it ideal for building highly scalable, real-time applications that can handle a large number of simultaneous requests.
• Single-threaded Architecture: Node.js operates on a single-threaded event loop, which means it can handle concurrent requests without the overhead of creating a new thread for each request. This lightweight architecture maximizes resource utilization and minimizes latency, resulting in faster response times and improved performance.
• Vibrant Ecosystem: Node.js has a rich ecosystem of libraries, frameworks, and tools, including npm (Node Package Manager), which is the largest ecosystem of open-source libraries in the world. This vast repository of modules enables developers to easily integrate third-party functionality into their applications and accelerate development.
