Yes, I Wrote That Thing 😭

Imagine writing your entire codebase in JavaScript just to avoid import tariffs. Time to start a black market for Python modules and Java libraries. "Yes officer, these are American-made classes, definitely not smuggled from Finland. The umlaut is just for aesthetics."

Remember when we used to manipulate the DOM with jQuery like it was some kind of magical superpower? Those were the days... Tom (vanilla JavaScript) chasing Jerry (jQuery) around the codebase, trying to catch that sweet syntax sugar that made everything so much easier. Now we've got React, Vue, and Angular while jQuery sits in the corner collecting dust like that USB stick with your first website. Pour one out for the library that saved us from IE6 compatibility nightmares and made us feel like wizards for writing $('#myElement').fadeIn() instead of 17 lines of vanilla JS.

The hill programmers are willing to die on: proper syntax terminology. Nothing triggers a developer faster than hearing someone call parentheses "brackets" during code review. It's the same energy as correcting someone's grammar in the YouTube comments section. The mock TED Talk format just makes it *chef's kiss* - because we all know that person who treats basic programming knowledge like they're delivering revolutionary wisdom to the masses.

JavaScript's type coercion is like that friend who tries to help but makes everything worse. Look at this beautiful chaos: typeof NaN returns " number " because obviously not-a-number is totally a number! Loose equality says true==1 but strict equality says true===1 is false. Make up your mind! Floating point? 0.5+0.1==0.6 is true but 0.1+0.2==0.3 is false. IEEE 754 strikes again! Math.max() with no arguments gives -Infinity while Math.min() gives Infinity . Peak logic. The masterpiece: (1+[]+[]+![]) has length 9 because it converts to "1" + "" + "" + "false" = "1false" And my personal favorite: true+true+true===3 is actually true because JavaScript converts booleans to numbers for addition! No wonder the creator is smirking. He unleashed this beautiful monster on us and now we're all stuck with it. And we can't even escape because the entire web runs on it!
