title: Separating vowels and consonants
body: <p>How can you separate vowels and consonants from strings, to create a filter? </p>
  
  <p>How can i replace the consonants and vowels with other letters</p>
  
  <p>I came up with this </p>
  
  <pre><code>(\A[^aeio]{1,3})(\w*)/
  </code></pre>
  
  <p>while searching online, but not sure exactly how it works past the filtering part of <code>^aeio</code>, to get consonants.</p>
