TED-Ed just released the first episode of a 10-part series called “Think Like a Coder.” It’s an animated adventure starring a teenager named Ethic who wakes up with amnesia in a prison cell and befriends a hovering robot named Hedge, who will do anything she tells it to do in the form of pseudocode instructions. In this first episode we learn about for, next, and while loops, which Ethic uses to get Hedge to pick some locks.
