// Using async/await const fs = require('fs').promises; async function readFile() { try { const data = await fs.readFile('file.txt'); console.log(data.toString()); } catch (err) { console.error(err); } } const passport = require('passport')

const user = new User({ name: 'John', age: 30 }); user.save((err) => { if (err) { console.error(err); } else { console.log('User saved successfully'); } }); const LocalStrategy = require('passport-local').Strategy

Node.js is built around asynchronous programming using callbacks, promises, and async/await. Understanding how to work with asynchronous code is crucial for building efficient and scalable applications.

passport.serializeUser((user, done) => { done(null, user.username); });
