The perfect regex tutorial doesn't exi— Seriously though, the chaotic jumble of special characters in regex patterns might as well be created by a cat walking across your keyboard. That cryptic pattern /^([A-Z0-9_\.-]+) showing up in the second panel? Yep, looks exactly like what happens when my cat decides to "help" with coding. The brutal truth is that most regex patterns look completely indecipherable until you spend hours decoding them. And even then, you're never quite sure if they'll match what you want or suddenly match your entire database and crash your app. Pro tip: Always test your regex on a small sample before unleashing it on production data. Unless, of course, you prefer the chaos of letting your cat write it.
