mentioned in about page [1] that Javascript regex flavor is used [1] https://regexcrossword.com/about https://regexcrossword.com/about

  Ah, I missed that. That really compounds the question though: I see that they explicitly recommend regex101, which claims that the clue is invalid JS regex

    probably they intended the user to choose JS on regex101 not sure about the question you hit a snag, can you post the details here? you might get your doubt cleared
    • lordgrenville 7y ago
      One of the clues on Beginner puzzle 4 is /+ Pasting that into regex101, with flavour Ecmascript, yields "Pattern Error" (rightly, since forward slashes enclose patterns, and thus need to be escaped).

        oh ok, got it and yeah, agree with you, this should either be escaped or some explanation added regarding delimiters
