JavaScript NaN Is Weird

Ah, the duality of random number generation! The top panel shows the proper way—importing libraries like random , time , or os to generate proper pseudo-random numbers with good entropy. The bottom panel reveals the chaotic evil approach—hardcoding your "random" generator without external input, which is basically just saying return 4 because it was randomly chosen by fair dice roll. Guaranteed to be random! The twisted face in the second panel perfectly captures the deranged energy of a developer who thinks Math.floor(Math.random() * 6) + 1 is too much work and opts for const getRandomNumber = () => 4; instead. Cryptographers are screaming somewhere.

So you're telling me that accessing an array with a negative index in JavaScript not only works but actually adds a property to the array? And then when you check the array, it shows you this cursed -1: 4 sitting there like it belongs? The bell curve perfectly captures the JavaScript experience: beginners think it's ridiculous (correct), experts also think it's ridiculous (also correct), but the middle crowd has Stockholm syndrome and will defend it with their lives. "It makes sense bro, everything in JS is an object!" Yeah, and that's exactly the problem. JavaScript treats arrays like objects because they are objects, so test[-1] = 4 is just adding a property named "-1" to your array object. It's technically in the spec, which somehow makes it worse.

First day of programming: "Let me just Google this regex real quick." Ten years later: "Let me just DuckDuckGo this regex real quick." The only thing that changes after a decade of coding is your search engine preference and privacy concerns. Regex remains the eternal mystery that no one bothers to memorize. It's like learning to fold fitted sheets – technically possible but why torture yourself?
