title: Is it possible to use a variable's value as an object key inside object declaration?
body: <p>I want to do something along these lines:</p>
  
  <pre><code>var firstName = "alan";
  var secondName = "antonella";
  var statusOfPeople = {
      firstName: "excellent",
      secondName: "superb"
  };
  console.log(JSON.stringify(statusOfPeople));
  </code></pre>
  
  <p>And get this output:</p>
  
  <pre><code>{ "alan": "excellent", "antonella": "superb" }
  </code></pre>
  
  <p>Is this possible? Without doing this?</p>
  
  <pre><code>var statusOfPeople = {};
  statusOfPeople[firstName] = "excellent";
  statusOfPeople[secondName] = "superb";
  </code></pre>
