title: Simplest way of checking vowels in a list of string
body: <p>I have the code</p>
  
  <pre><code>List&lt;String&gt; words
  </code></pre>
  
  <p>There is only currently 2 counted words in the list which are: [0] "abc", [1] "abc"</p>
  
  <p>What is the simplest way of going through the list and checking if a vowel exists in these words?</p>
