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 :)
