Recently I have been busy with nodejs and I thought to create something like this Java input library, so I started with some rough code like below:'use strict';const readline = require('readline');const fs = require('fs');class StdIn {  constructor(opt_name) {    this.name = opt_name;    this.rs = this.name ? fs.createReadStream(this.name) : process.stdin  }  readInt(callback) {    this.rs.on('data', (chunk) => {      let line = chunk.toString();      let numbers = line.trim().split(/\s/);      numbers.forEach(num => {        callback.call(this, num);      });    });    this.rs.on('end', () => {      process.exit(0);    });  }  readLine(callback) {    this.rs.on('data', (chunk) => {      let line = chunk.toString();      callback.call(this, line);    });    this.rs.on('end', () => {      process.exit(0);    });  }}const stdIn = new StdIn(process.argv[2]);//stdIn.readInt(num => {//  console.log(num);//});stdIn.readLine(line => {  console.log(line);});Its working fine till now and buts its still incomplete and the code is too messy, the problem clearly visible here that I am trying to push event oriented code into my object oriented world, I am confused basically for two things:It is practical to do so?If yes then what would be the best way?
Input-reading library for Node.JS
javascript;object oriented;node.js;io;callback
