Short description

CLI apps teach input/output streams. Use `readline` to ask questions and compare answers.

Simple quiz

const readline = require('readline');
const rl = readline.createInterface({ input: process.stdin, output: process.stdout });

rl.question('Capital of France? ', (answer) => {
  console.log(answer.trim().toLowerCase() === 'paris' ? 'Correct!' : 'Wrong');
  rl.close();
});
