Non-blocking Asynchronous I/O
Node.js follows an event-driven, non-blocking I/O model, making it highly efficient for applications that require extensive I/O operations. Unlike traditional synchronous programming models, where each operation waits for the previous one to complete, Node.js executes multiple operations concurrently without blocking the main execution thread.
- Perfect for real-time applications such as live chat, online gaming, stock market tracking, and collaborative tools.
- Optimized for API handling – Node.js can efficiently handle thousands of concurrent API requests, making it ideal for microservices and cloud-based architectures.
- Great for streaming applications – Its ability to process data in chunks allows for seamless video streaming, music playback, and file uploads.
