As far as I can see, it's not. Also, I checked and didn't see any other similar issue, so it is not a duplicate.

The examples and explanations in these steps have been updated. β¨

Sorry to do this again, but in the new description: "The first group is a non-capture group. Therefore it cannot be referenced.", but the first part of regular expression is (ha)-\1
. It is a capturing group and it uses a reference.

You're right, I just noticed it now. I think the texts got mixed up. I'm updating to the latest it should be. Can you please review again? @Neinei0k
Thanks for your feedback. β¨

I think it should be made clear that \1
means that it matches the same text that the first group matches. Someone who never used regular expressions might not get this from this description. Particularly the usage of words "to avoid rewriting" could be interpreted the same way as it was before all the changes, that \1
could just be replaced by the contents of the capturing group, which is obviously wrong. Maybe write something like "\1
will be substituted with the text matched by the first capturing group".
