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 Equality: A Horror Story

JavaScript's Equality: A Horror Story
OH. MY. GOD. Welcome to the JavaScript circus of horrors where zero equals a string of "0.0" but zero with an 'n' doesn't?! And then—PLOT TWIST—the string "0.0" with a NOT operator suddenly equals zero with an 'n'?! 💀 This is the EXACT moment your brain cells commit mass suicide during a coding session. JavaScript's type coercion is like that toxic ex who keeps changing the rules mid-argument. "Yeah, that makes sense" turns into "WHAT THE ACTUAL HELL IS HAPPENING" faster than you can say "use TypeScript instead."

How To Spot If A Commenter Is A Programmer

How To Spot If A Commenter Is A Programmer
Regular humans: *uses == to check equality* Programmers: *scoffs at ==, uses !== instead because type coercion is for the weak* Enlightened programmers: *monocle gleams* "I exclusively use the != operator with a logical NOT before my expression to assert truthiness while simultaneously inverting the result, thus proving my intellectual superiority." The evolution of operator snobbery is the true mark of a developer's journey. Next level: writing custom equality functions that take 27 parameters.

JavaScript NaN Is Weird

JavaScript NaN Is Weird
JavaScript's equality comparison is like that one friend who can't decide what they want for dinner. The console shows NaN === NaN returning false because in JS, each NaN is its own special snowflake. Two identical-looking "not a number" values? Nope, completely different according to JavaScript! The corporate "spot the difference" meme perfectly captures the absurdity - there's literally no difference between the two NaN cards, yet JavaScript insists they're not the same. It's the programming equivalent of gaslighting. Next time someone asks why developers drink, just show them this.
