Which Of These Javascript Expressions Is False?

Which Of These Javascript Expressions Is False?
The ultimate JavaScript trivia nightmare! Every single option here is a trick question showcasing JavaScript's bizarre type coercion and equality rules: A: typeof null === 'object' is actually TRUE - a notorious JS bug that's been around since the beginning. Null isn't an object, but returns 'object' when typeof'd. B: Math.min() > Math.max() is TRUE too! Without arguments, Math.min() returns Infinity while Math.max() returns -Infinity. C: NaN === NaN is FALSE - the only value in JavaScript that isn't equal to itself! D: 0 == "" is TRUE because JavaScript type coercion converts empty strings to 0. The contestant's face says it all - the answer is C, but knowing JavaScript, you'd question your entire programming career before answering.

JavaScript's Quantum Logic: NaN Is A Number

JavaScript's Quantum Logic: NaN Is A Number
JavaScript's type coercion strikes again! In JS, NaN (Not a Number) is technically categorized as a "number" type. Check it yourself with typeof NaN and watch your sanity slowly dissolve. It's like labeling a vegetarian restaurant "meat" because it's a food-related establishment. The wide-eyed shock on that cat's face perfectly represents every developer's reaction when discovering this cosmic joke buried in the language spec. The ECMAScript committee is probably still giggling about this one.

JavaScript, you absolute TROLL! 🙄 First you tell us NaN stands for "Not A Number" and then have the AUDACITY to claim its type is 'number'?! The BETRAYAL! The DRAMA! The INCONSISTENCY! It's like JavaScript is gaslighting its own developers with this nonsense. "I'm not a number, but also I AM a number." Pick a lane, JavaScript! This is why developers need therapy!

JavaScript: "NaN stands for 'Not A Number'" Also JavaScript: typeof NaN returns 'number' This is peak JavaScript energy right here. The language literally created a special value to tell you something isn't a number, then categorized it as a number. It's like labeling a vegetarian dish "Contains No Meat" and listing the first ingredient as beef. Just another day in JS wonderland where nothing makes sense and we're all pretending it's fine.
