Which Regex Implementation Does Discourse Use?

In case anyone else stumbles upon this thread,
I encourage you to check out:

How to use Discourse regexes with watched words?

Reading that, I don’t see much about them except to see that they are Javascript regular expressions. (I would have assumed Ruby without that link.) So a Javascript reference would be in order. Which has internal links to specifications, if you want to go deeper.

I assumed wrongly just like @elijah over there: it’s actually Javascript-flavored.

Reach out to one of them if you’re still stuck
