Regex is not a universal language. You are using some constructs only available in PHP/PCRE (see what I changed below) and not JavaScript.

This regex is about the same, working in either version: if\s*\(((?:[^\(\)]|\((\1)\))*)\)\s*{((?:[^{}]|{(\2)})*)}

What I changed

(?1) becomes (\1) (same with 2)

*+ becomes *

Note: I removed the backtracking control sequence: *+, so I wouldn't be surprised if this catastrophically backtracks with some inputs.
