What are the main components included in the Node.js structure?

The main components of the Node.js architecture include:

• V8 JavaScript Engine — the engine that executes JavaScript code. Node.js uses the V8 engine from Google Chrome.
• libuv — a library that provides asynchronous I/O, event loop, and work with the file system, network, etc.
• Node.js API — a set of modules and functions that provide access to the file system, network, streams, processes, and other system resources.
• Event Loop — a mechanism that handles asynchronous operations and callbacks.

This architecture allows Node.js to efficiently handle a large number of concurrent connections with minimal resource consumption.
