Since JavaScript is not compatible with PCRE, some useful features (such as Lookbehind, If-Then-Else Conditionals, etc.) are not supported, regular expressions that use these features cannot be parsed by JavaScript's regular expression engine. This PR optimization the syntax of these regular expressions ensures that JavaScript handles them correctly.
Thanks @fy0 for pointing this out.
