Regular Expression Pocket Reference, 2nd Edition

JavaScript

JavaScript introduced Perl-like regular expression support with version 1.2. This reference covers versions 1.5 through 1.7 as defined by the ECMA standard. Supporting implementations include Microsoft Internet Explorer 5.5+ and Firefox 1.0++. JavaScript uses a Traditional NFA match engine. For an explanation of the rules behind this NFA engine, see "Introduction to Regexes and Pattern Matching.”
