How does Node.js work?
Node.js is a runtime environment that executes JavaScript code outside of a web browser. It is based on the V8 JavaScript engine developed by Google.
Key Points:
- Non-blocking I/O: Node.js is known for its asynchronous and event-driven architecture, which allows it to process multiple requests simultaneously without blocking the execution of other tasks.
- Single-threaded: Despite being single-threaded, Node.js can handle concurrent operations by utilizing event loops and callbacks.
- Modules: Node.js has a module-based system that enables developers to modularize their code and reuse components across different applications.
