title: Discord Bug Error Invalid Token in discord.js
body: <p>So I want to create a bot discord for fun in JavaScript using discord.js.</p>
  <p>I wrote this code:</p>
  <pre><code>const Discord = require(&quot;discord.js&quot;)
  const client = new Discord.client()
  
  client.once('ready',() =&gt; {
    console.log(&quot;Ready !&quot;);
  
  });
  
  client.login('token');
  </code></pre>
  <p>But when I'm trying to run it, I get this error:</p>
  <blockquote>
  <p>/home/runner/MelodicPlainApplicationprogrammer/node_modules/discord.js/src/rest/RESTManager.js:32
  const token = this.client.token ?? this.client.accessToken;
  ^
  SyntaxError: Unexpected token '?'</p>
  </blockquote>
  <p>This is on repl.it, and when I'm in VSCode, it works.</p>
  <p>Why?</p>
