Non-Blocking I/O: Node.js uses a non-blocking, event-driven architecture, which means it can handle multiple requests simultaneously without waiting for any of them to complete.

Efficient Resource Use: The asynchronous nature of Node.js allows it to perform well even with limited resources, making it suitable for microservices and applications that need to scale horizontally.

Powered by V8 Engine: Node.js is built on Chrome's V8 JavaScript engine, which compiles JavaScript directly to machine code, resulting in fast execution times.
