title: Node.js readline: Unexpected token =>
body: <p>I am learning node.js and need to use <code>readline</code> for a project. I have the following code directly from the <a href="https://nodejs.org/api/readline.html" rel="noreferrer">readline module example</a>. </p>
  
  <pre><code>const readline = require('readline');
  
  const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
  });
  
  rl.question('What do you think of Node.js? ', (answer) =&gt; {
    // TODO: Log the answer in a database
    console.log('Thank you for your valuable feedback:', answer);
  
    rl.close();
  });
  </code></pre>
  
  <p>But when I run the code via 
  <code>node try.js</code> command, it keeps giving out the errors like below: </p>
  
  <pre><code>rl.question('What is your favorite food?', (answer) =&gt; {
                                                      ^^
