title: If variable is equal to value or another value - javascript
body: <p>I'm trying to write a simple Pig Latin code. I want to check if the first letter of the input string is a vowel, if so then to run that certain code. How can I ask if y is equal to one of those values. </p>
  
  <pre><code>function pigLatin() {
      var y = prompt("Enter a word:")
      if (y.charAt(0) = a,e,i,o,u) {
          var pigLatin = y + "ay";
          document.getElementById("answer").innerHTML = "Answer is: " + pigLatin;
      } else {
          var wordLength = y.length + 1;
          var pigLatin = y.substring(1, wordLength) + y.charAt(0) + "ay";
          document.getElementById("answer").innerHTML = "Answer is: " + pigLatin;
      }
  }
  </code></pre>
