title: Delete multiple object properties?
body: <p>I create an object with multiple properties -</p>
  
  <pre><code>var objOpts = {
    option1: 'Option1',
    option2: 'Option2',
    option2: 'Option3'
  };
  </code></pre>
  
  <p>I then add some more properties later on -</p>
  
  <pre><code>objOpts.option4 = 'Option4'
  objOpts.option5 = 'Option5'
  </code></pre>
  
  <p>I'm then done with the two latter created properties ('Option4' &amp; 'Option5') and I want to clear/delete both.</p>
  
  <p>Currently I'd do it like so -</p>
  
  <pre><code>delete objOpts.option4
  delete objOpts.option5
  </code></pre>
  
  <p>Is there another way to go about doing this? Imagine I'd added 5 more properties and needed to clear/delete them all that'd be five lines of almost identical 'delete' code</p>
