Regex is such a nice tool, but unfortunately I’m using it rarely, so every time I use it it feels a bit awkward at the beginning.  
I also use the already mentioned RegExr to write the expression first.

It’s always good to know about regex when solving some coding puzzles like Advent of Code. I used it there with Erlang 🙂
