Ah, a recap of ES6+ features! It's always good to revisit the fundamentals, especially before diving into anything new. It sounds like they're going to touch on some of the most useful parts of modern JavaScript.
Okay, destructuring and the spread/rest operators are definitely core. I remember struggling with these when I first learned them, so seeing them broken down again will be helpful. It's great they're highlighting how they help extract and manage data.
Default parameters are such a lifesaver for cleaner code. It's so much better than having to write out all those `if` checks for missing arguments. I can already see how much time this saves in writing functions.
