Study Notes
Node.js Components
- Node.js leverages two fundamental components: V8 JavaScript engine and libuv library
V8 JavaScript Engine
- Primary responsibility of V8 JavaScript engine is to execute JavaScript code
Non-Blocking Execution
- Node.js enables non-blocking execution of asynchronous operations through its event-driven, non-blocking I/O model
libuv Library
- Primary responsibility of libuv library is to provide an asynchronous I/O interface
- libuv library's feature of thread pooling enables Node.js to handle CPU-bound tasks efficiently
Node.js Capabilities
- V8 JavaScript engine and libuv library together provide Node.js with the ability to execute JavaScript code and handle I/O operations efficiently
