What's The Point

Someone took their TypeScript generics knowledge and applied it to the most important problem in computer science: categorizing anime characters by gender presentation. Because nothing says "I understand covariance and contravariance" quite like explaining why that cute anime character might be a trap. The progression is beautiful: simple generic Girl, then a Variant that could be Boy OR Girl (Schrödinger's waifu), then a Boy that implements the IGirl interface (the classic "looks like a girl, sounds like a girl, but surprise"), and finally void—because some things transcend mortal understanding. The BitCast at the end is the cherry on top: when type safety fails you, just reinterpret those bits and pray. Your type system can't save you now.

Look at those semicolons switching sides! The top code shows the classic "sad" C-style syntax where semicolons terminate statements. But the bottom shows the "happy" syntax from languages like Swift where colons come before the parameter instead of semicolons after. It's like the difference between ending a conversation with "Goodbye." and starting one with "Hey friend: what's up?" The second just feels more welcoming! Punctuation therapy for your code.

Ah, the eternal cycle of library addiction! You find that shiny new package that solves all your problems (or so you think), and suddenly you're evangelizing it like you've discovered fire. Meanwhile, your codebase is already a digital hoarder's paradise with 1000 dependencies, and your coworkers are plotting your "accidental" deletion from the Git contributors list. The best part? Next week you'll be doing it all over again with another library because clearly, the solution to dependency hell is... more dependencies!

OH. MY. GOD. The absolute HORROR of discovering TypeScript's any type! It's like watching a train wreck in slow motion but being POWERLESS to stop it! 💊 Fresh-faced TypeScript devs staring longingly at that magical pill labeled "any" that promises to make ALL their type errors vanish into thin air! Sure, honey, just sprinkle some any on that complex interface and POOF! – your compiler stops screaming at you! Who needs type safety when you can have BLISSFUL IGNORANCE?! It's the gateway drug of TypeScript – one minute you're using it "just this once to make the error go away," and the next thing you know, your entire codebase is a typeless wasteland. The BETRAYAL! The DRAMA! The TECHNICAL DEBT!

Ah, the sacred art of variable naming. When your brain sees userId , it reads "user ID." But when it sees userid , your inner voice screams "USER-id???" like some confused database goblin. This is the hill many senior devs choose to die on after years of staring at poorly named variables. We'll spend 15 minutes in code review arguing about capitalization but somehow let that 500-line function with no comments slide right through.
