JavaScript is weird and that’s why we love it. In this talk, we’ll explore the strangest, funniest, and most broken behaviours hiding in JS and browser APIs. From [] == ![] being true, to overwriting the user’s clipboard with a single line of code, this is a tour of JavaScript’s most “beautiful” chaos.
