title: Differences between regular expressions in Java and ECMA-262 (AS, JS)
body: <p>I need to convert Java regular expressions into Actionscript regular expressions.</p>
  
  <p>There apparently aren't any premade converters, so I'm trying to write one myself. Is there any resource that'd list all the differences?</p>
  
  <p>I'm aware of regular-expressions.info, but there doesn't seem to be a comprehensive listing of differences there.</p>
  
  <p>Thanks</p>
