Why not? They're just strings until they're compiled. "Code is data"

- CaptainMarvel 7y agoThe thought of doing this literally didn’t occur to me... I think this is great!
- jazzyjackson 7y agoWell I suppose the r in front of them in python made them look just enough "not a normal string" for me to forget how the + operator might act. My day-to-day experience is in nodejs, where adding one regex object to another coerces them to normal strings first [edit: hey neat, the hackernews form strips emoji from comments, I wonder if that's just ranges of unicode or if there's some crazy regex going on :D]
- baudehlo 7y agoIn Javascript you just need to wrap in `new RegExp(r1 + r2 + r3)`.
