History of 2019-10-12 Challenge accepted - a Node.js grep

11:58 UTC Revision 1 . . . . Marcin BorkowskiAn old friend of mine posted a challenge on Twitter to implement a grep-like utility in one’s language of choice. Instead of complaining that he’s got an unfair advantage – he is a Pythonista, and Python is almost as well-suited to that kind of tasks as Perl – I decided to accept the challenge. Of course, I had to start with Emacs Lisp.
