title: Why executing ('Hello','world!) returns 'world!'?
body: <p>I'm learning programming with JavaScript, and I just don't know what's happening here:</p>
  
  <pre><code>let myVar = ('Hello','World!');
  console.log(myVar);
  </code></pre>
  
  <p>The output is:</p>
  
  <pre><code>World!
  </code></pre>
