title: How do I remove duplicate values from a Coldfusion array?
body: <p>I have a function that receives a string of tags. In order to save the tags individually, the function transforms the string into an array:</p>
  
  <p><code>this.tags = listToArray(this.tags, ", ");</code></p>
  
  <p>How do I remove duplicate values in the event that there are any?</p>
