Hello. I updated my ebook on JavaScript regular expressions [1] today - updates include corrections, additional content, exercises, solutions, etc All my ebooks [2] are currently free to help with quarantine reading. These include GNU grep & ripgrep, GNU sed, GNU awk and three books on regular expressions - Python, Ruby, JavaScript I'd appreciate your feedback and hope the books are useful. Happy learning :) [1] https://github.com/learnbyexample/learn_js_regexp [2] https://learnbyexample.github.io/books/

While on the subject of RegEx, I'll just recommend this website. It's great for practicing RegEx and interactively seeing what changes to your expression are doing and why: https://regex101.com/ https://regex101.com/

  Yep, that website is a good way to interactively solve/learn. The site also includes quiz, cheatsheets, etc. I mention it in an interlude chapter, along with regexr[1], regulex [2], debuggex[3] and regexcrossword [4] [1] https://regexr.com/ https://regexr.com/ [2] https://jex.im/regulex/ https://jex.im/regulex/ [3] https://www.debuggex.com/ https://www.debuggex.com/ [4] https://regexcrossword.com/ https://regexcrossword.com/

Thank you for sharing your work! It looks quite wide-ranging and in depth.

  Thanks for posting clickable links and feedback about the markdown sources. I use pandoc to convert markdown to pdf/epub and my initial learning with pandoc [1] resulted in single file usage. So, I kept it like that. I'm planning to create a separate chapter-wise branch so that I can publish a nicer web version with tools like mdBook [2]. This will require a bit of scripting to handle references across chapters.
