Line Up the Boxes
by Anonymous · ⭐ 1 · 🍴 0
📦 One value fits in one box, but what about many? Line them up and give each an index! Try push, pop, unshift, and shift—see how adding to the front shifts all numbers, while adding to the back keeps them in place. You'll instantly see why counting starts at 0! 🔍 In "Step-by-Step", watch a loop visit each box to calculate totals, find max values, count items, locate positions, or double numbers. 🎯 "Target Match" has 6 puzzle levels where you create target lines in as few moves as possible. Built with code—remix it to make your own box lineup!
