The worst code: - Duplicates large, dumb patterns in slightly different ways throughout - Lacks coherent naming or compartmentalization: it's just a pile of shit (statements or expressions) - Lacks testing - Is difficult and unpleasant to read - Is ugly: not formatted, inconsistently formatted, and lacks any sort of regularity - Combines many functions into god objects and god functions without clear intent. Who knows what any of that crap is supposed to do, or if it's even doing anything correctly - If not lacking comments, contains useless boilerplate comments that take up visual real estate - Verbosely reinvent low-level constructs poorly - Live as numerous, fragile, interdependent pieces scattered across many files and time (runtime) - Are configured in unclear and confusing ways that create incompatible states that break - Includes code that is never used - Contains fragments of experiments that were never discarded - Combined and abstracts over opaque units of other junk that doesn't behave properly - Doesn't sanitize untrusted input - Doesn't give the user sensible feedback - Makes the user do unnecessary steps themselves - Acts in unpredictable ways - Tries to solve a problem that never needed solving to begin with - Prematurely optimizes the previous
