Starting launch school.</p> <p>I'm starting with Ruby and did a lesson on Arrays this morning. I also created a little AI teaching assistant to help when I don't understand something (it's amazing - highly recommend).</p> <p>I always ask for real world examples for better comprehension. I hate school examples like using the Fibonacci sequence to learn recursion.</p> <p>But a quick chat with Claude taught me how recursion is incredibly helpful for e-commerce platforms with big product catalogs. Think Amazon, Wal-Mart, etc. </p> <p>Where they have Home, Electronics, Grocery, Outdoor. In electronics there's gaming, appliances, tv.
