I do not believe there is a 3rd party polyfill for lookbehind as it is quite tricky to implement regular expressions. If you found one, please let me know. Thanks in advance.

There's always this: https://xregexp.com/

But it's not really a polyfill, just a library.

On mobile and can’t tell whether xregexp still doesn’t have lookbehind, but in case it doesn’t I found this: https://github.com/beaugunderson/xregexp-lookbehind
