This is an experimental โbookโ about regular expressions. It is largely visual and example-based, as opposed to most regex resources I found while I was learning. I also attempted to choose test cases that highlight some common gotchas. I think itโll be worth your time.
This bookโs intended audience is regex beginners. Some programming experience is assumed. It does not go into advanced regex concepts like engine backtracking and recursive regexesโat least not at the moment.
This is also an open source project, and contributions are welcome.
Thanks for taking the initiative to contribute to REFRF! ๐
