Alex, I'm confused as to what regular expressions would help with in this case. (Over .indexOf) The idea of .util() would be to return a new string which is just a substring, but provided as an "ease of use" to the developer.
The case where I wrote .util() was in parsing out two comma separated values. I only needed the first, as could also be seen with trying to pull the first name (assuming just a first and last name), you could easily call name.until(' ') and get that back.
