So, you want to build a "Fast Lock-Free Queue in Modern C++" from scratch? 🚀 Great idea! Because who doesn't want to spend their weekend reinventing a wheel that's already faster, shinier, and exists in every programming library since the dawn of time? 🛞🙄

It's on: JagJam, the gamejam for the Atari Jaguar, started today. If you'd like to code a game for one of the most unique systems of the 90s that initially awed id Software's John Carmack, provoked Sega to rush their 32X to market and even got Sony briefly taking notice while they were finishing their Playstation, this is your chance! 😎 Thanks to Songbird Productions and @ctrlaltrees for being part of this year's JagJam again. And don't worry if you don't have that much time: JagJam runs until the end of October, so you've got six months to go. Looking forward to your entries! 🥳 Please spread the word if this whole thing is something you'd like to see getting more attention. Cheers!

You Can Use Same Variable Name TWICE?!
🔥 NO WAY! Destructuring allows DUPLICATE variable names in the same statement! const {a, a} = obj is VALID JavaScript! Last one silently wins. ESLint doesn't catch this by default. Tag a dev who needs to see this!

flatMap Can Filter AND Transform?!
flatMap is a SECRET WEAPON! Return empty array to REMOVE items, return array with value to KEEP. One pass does filter AND map together! This trick will make your code 10x cleaner!

Promise.resolve UNWRAPS Thenables?!
Promise.resolve has RECURSIVE unwrapping! Any object with a 'then' method gets called. Nested thenables unwrap ALL the way down until a real value appears. This automatic unwrapping will confuse your async code!

Arrow Functions Have NO arguments?!
Arrow functions BREAK arguments! They don't have the arguments object. This will cause ReferenceError when you try to use it. Regular functions work, arrows don't!

HAVING Filters After GROUP BY?!
HAVING filters GROUPS, WHERE filters ROWS! HAVING runs after aggregation, WHERE runs before. This order matters and will break your logic!
