Node.js Architecture: How It Works

The secret behind Node.js lies in its unique architecture:

1️⃣ Single-Threaded Event Loop: Unlike traditional multi-threaded models, Node.js uses a single thread for all operations, relying on asynchronous programming to handle multiple requests.

2️⃣ Non-Blocking I/O: All I/O operations (e.g., file reads, database queries) are non-blocking, ensuring high performance under heavy loads.

3️⃣ Event-Driven: Events and callbacks keep the system responsive, ideal for building real-time applications.

4️⃣ V8 Engine: Node.js uses Google’s V8 engine for executing JavaScript, offering speed and efficiency.

Thanks to this architecture, Node.js is perfect for chat applications, APIs, and streaming platforms.
