Node.js is known for its non-blocking architecture powered by the event loop. Instead of creating new threads for every request, Node.js uses asynchronous callbacks and a single-threaded event loop to handle multiple requests efficiently.
Why non-blocking architecture matters
Applications such as APIs, chat apps, and streaming platforms benefit greatly from Node.js because it can handle thousands of concurrent connections.
Node.js changed backend development by making JavaScript a server-side language.
