title: Can I run an uppercase method on an object?
body: <p>I have an object. Is there a way to run toUppercase on all of its keys?
  What I'm doing is trying to uppercase every element in this object</p>
  
  <pre><code>JSON.stringify(JSONObj.people).toUpperCase()
  </code></pre>
  
  <p>I haven't gotten the above command to work for me. I'm a bit new to this, so appreciate any help!</p>
