Build a Reusable Scene

Good programmers don't repeat themselves. Write one function that builds an entire scene, then call it with different inputs to make different worlds.

1. 1A small helper

   Write walkTo(name, distance) that walks and then waves.

   function walkTo(name, distance) {
     moveForward(name, distance)
     wave(name)
   }

2. 2A scene builder

   Write makeScene(hero, sidekick) that creates both and walks them.

3. 3Two worlds

   Call makeScene once — then change the names and run again.
