title: Can you use JavaScript "in" operator to test for multiple conditions?
body: <p>I'm trying to test if one or more strings is equal to an object key. For example:</p>
  
  <pre><code>if(("apple" || "oranges) in fruitObj) {
      console.log(fruitObj);
  }
  </code></pre>
  
  <p>My end goal is to loop through all the strings in an array, and test if any of the strings are inside "fruitObj".</p>
