Node.js Event Loop, V8 Engine & Asynchronous Architecture

The Node.js Non-Blocking Event Loop

Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient for real-time web applications.

const fs = require('fs/promises');

async function readFileExample() {
    try {
        // Asynchronous non-blocking file read
        const data = await fs.readFile('package.json', 'utf8');
        console.log('File content loaded without blocking the event loop!');
    } catch (err) {
        console.error('Error reading file:', err);
    }
}
readFileExample();
