I recommend learning Regex if for no other reason than pulling off complex searches (and search and replaces) in code editors. A few Regex tricks can turn an otherwise tiresome "find, check, and replace in all the files" to an automated search and replace function. Great to see more content helpers coders get to that point!
Yes! This is probably my number one use case as well; that, and trying to extract data from HTML or other messy data 😯 which I know, I know, isn't a good use case (I even say so in the post!) but for one-off tasks it's really powerful.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
