Great explanation of array flattening! The way you covered .flat() and its practical uses was super clear. I’ve always found flattening nested arrays to be one of those tasks that’s deceptively tricky at first but so satisfying once you get the hang of it. Have you ever tried using .reduce() for flattening as well? It’s an interesting alternative! I’ve been exploring similar JavaScript topics recently, and it’s always exciting to see content like this. Awesome work!
