title: How to replace everything after first instance of character in a string
body: <p>I want to remove everything except the words before the first comma in a string containing several comma-delimited values:</p>
  
  <p>ie - Value One, Value Two, Value Three, Value Four</p>
  
  <p>I am looking to isolate only "Value One" and return it.  The values are different across several strings with the same format, so I want to replace based on the first comma as opposed to replacing specific values.</p>
  
  <p>Thanks.</p>
