Hi, very nice RegEx educational site/book. Feedback: - In the chapter https://refrf.shreyasminocha.me/chapters/character-classes https://refrf.shreyasminocha.me/chapters/character-classes an example is given which uses: o ^ character outside brackets o $ end of line o + But the explanation above does not introduce these yet, so a real beginner user (like me) is lost. The ambigious characters example is fine, since it uses all the concepts already explained.
