I built PeelCode because I was tired of how most JavaScript learning platforms explain closures without making you feel them. Every tutorial repeats the same examples — “makeAdder,” “counter,” “setTimeout” — but few actually peel back why closures behave the way they do when things get messy. PeelCode: Closures is different. It’s not a tutorial — it’s a sandbox of real, tricky closure scenarios that force you to reason like the JavaScript engine itself. You don’t just read the answer — you experiment, break things, and see the invisible scopes come to life. What’s unique here: 💡 Challenge-first design — You start with code that puzzles you, not code that teaches you. 🔍 Layered explanations — Every solved challenge reveals the deeper mental model behind closures, step by step. ⚡ Instant feedback — A live code environment that responds to every tweak, so you learn by doing, not guessing. 🧠 Built for real devs — The problems aren’t classroom examples; they’re the ones that trip up even senior engineers in production. What I’m most proud of is how PeelCode bridges intuition and depth. It helps you see closures not as a “JS trick,” but as a powerful tool for encapsulation, memory control, and elegant design. If you’ve ever said “I understand closures” but still hesitate under the hood — this is your test. Come peel it layer by layer. 🍊
