JavaScript NaN Is Weird

javascript-memes, nan-memes, equality-memes, comparison-operators-memes, programming-logic-memes | ProgrammerHumor.io

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.

Branch Protection Won't Save Your API Keys

The security admin proudly sets up branch protection requiring admin approval for all code changes. Meanwhile, the intern is confused about needing a +1 approval while the senior dev is like "lgtm, ship it" despite the code clearly containing an API key hardcoded in plain text with debugging logs printing credentials. Security theater at its finest - the branch is protected but the data sure isn't.

When Your Ride-Share App Has An Existential Crisis

OH. MY. GOD. The absolute HORROR of receiving this text message! 😱 It's like the entire programming apocalypse packed into a single notification! When your ride-sharing app has a complete meltdown and starts spewing raw code errors instead of actual information. "NaN minutes" because time is now just a meaningless concept, "[object Object]" because who needs actual driver information anyway, and "license plate undefined" because identifying vehicles is SO last century. This is what happens when the developer tests NOTHING and ships everything. Somewhere, a backend engineer is having heart palpitations while frantically scrolling through Stack Overflow.

Content I Spent a Week in the Forest Coding JavaScript. With No Electricity. Last week, I decided to take a break from the hustle of the city and go back to nature. I packed my bags and headed into the forest. I left my laptop at home. But I couldn't help myself - I brought pen and paper. And I'm glad I did, because I ended up spending the week coding JavaScript. I had to start from scratch, of course. I mean, there's no way I could have remembered all the APIs and libraries. But it was a great opportunity to really get back to basics and learn how everything works. That's why I decided to start my own business. If you're looking for a truly immersive coding experience, look no further! For just 999USD a week, I'll take you into the forest and teach you everything.
