Ah, the apocalyptic quartet of syntax that makes developers question their career choices! Double equals comparing to true is like wearing socks with sandals - technically works but why would you do that? Just use the boolean directly! The null check with ?? that shows up uninvited in every codebase like that one relative at family gatherings who keeps asking why you're still single. Double exclamation marks on booleans - because apparently one wasn't dramatic enough to convert values to boolean. It's the coding equivalent of saying "REALLY REALLY" to emphasize your point. And that empty for loop with just a semicolon? Pure chaos. The kind of code that makes senior devs develop eye twitches during code reviews. These four horsemen don't just signal the end of readable code - they're the reason why Stack Overflow exists.

Ah, the classic "let me check every possible capitalization pattern" approach! This developer is manually checking for true , True , TRue , TRUe and then the same for false variants instead of just using toLowerCase() once and comparing to a standard value. The function even returns maybe if neither pattern matches, which is both hilarious and terrifying for Boolean logic. Somewhere, a computer science professor is feeling a disturbance in the force. This is the kind of code that makes code reviewers develop eye twitches and start muttering "string.toLowerCase() === 'true'" in their sleep.

The infamous "sleep sort" algorithm—where your array gets sorted by setting timeouts based on each value. The smaller numbers wake up first, the bigger ones hit snooze longer. Technically it works (sort of), but try explaining this beauty in a coding interview and watch the interviewer's soul leave their body. "It's O(max(array)) time complexity, sir!" Absolute chaos masquerading as computer science. The perfect algorithm if your requirements include "must be completely unreliable" and "please never use in production."

The eternal struggle between doing things right and doing things that work. Instead of using parseInt() or Number() like a civilized developer, this mad genius is just removing the quotation marks with replaceAll() to convert a string to a number. It's the coding equivalent of using a hammer to screw in a lightbulb - horrifying yet somehow it works. The face on the left is every senior dev witnessing this crime against programming humanity, while the face on the right is the junior who's just proud they "solved" the problem without reading the docs.
