Idk why I come too much late on your channel😢... Your way of explanation and your videos are awesome man❤❤

[@osamaxz5720]

thanks for explaining bro ❤ I'm a frontend developer now learning node js for backend so I'm familiar with pyramid of DOM or callback hell so what I do to solve this problem is promisfing the functions and use async await like to read file async I made this function async function readFileAsync(path, options) { return new Promise((res, rej) => fs.readFile(path, options, (err, data) => { if (err) { rej(err); } else { res(data); } }) ); } now to read specific file async function readTest() { try { const data = await readFileAsync('./test.txt', {encoding: 'utf-8'}) console.log(data) } catch(err) { console.log(err.message) } } and it's easy at is :)

const util = require('util'); const readFileAsync = util.promisify(fs.readFile); // ***** Direct utilizing promises ***** readFileAsync('./inpu.txt', 'utf-8') .then(data => { console.log(data); }).catch(error => { console.log(`${error}`); }) // ***** Using await/async ***** async function readFiles() { try { const data1 = await readFileAsync('./input1.txt', 'utf-8'); const data2 = await readFileAsync('./input2.txt', 'utf-8'); const data3 = await readFileAsync('./input3.txt', 'utf-8'); console.log(data1, data2, data3); } catch (error) { console.error(error); } } readFiles(); Please correct me if i am wrong.
