This is really cool Sundeep, thanks for doing this! Question for you: what did you use to draw the diagrams for the "Javascript Regex" book, such as on the cover? Thanks!

That is known as railroad diagrams and provided by sites such as regulex[0] (which I used for js cover) and debuggex [1]. I've also mentioned it in acknowledgements within the book.
