I use regex operators a lot. Like a LOT. It pretty much is my go-to for all my complex filtering and searching solutions. It runs extremely fast and extremely flexible since it takes dynamic expressions. I use it for the detecting conditionals in the form builders in my Bubble apps.
Anyway the point of this post is to remind myself and any who read this to always remember to escape special characters in your regex expressions. After so many uses I still forget this every once in a while.
