What is Node Js ?
choice for building scalable, real-time web applications. One of its key features is its asynchronous and
non-blocking I/O model, which enables efficient handling of multiple concurrent connections, making it
well-suited for applications that require high concurrency and responsiveness.
Node.js utilizes an event-driven architecture, operating on a single-threaded event loop, which allows it to
handle numerous simultaneous connections without the need for spawning multiple threads for each connection.
This characteristic ensures high efficiency and performance for real-time applications.
