title: How to find words containing a certain letter with Regular Expressions?
body: <p>I need a regular expression to find any words containing the letter "y".</p>
  
  <p>This was my idea:</p>
  
  <pre><code>/\bw*[y]\w*\b/
  </code></pre>
  
  <p>a word boundary, something or nothing, y, something or nothing, word boundary.<br>
  It works for the first word, but not for the next one.</p>
  
  <p>How do I get all the words containing a y within a string?</p>
