Fish Swims Three Times

Bubbles wants to cross the reef in three big strokes. You could write the swim line three times... or you could learn the shortcut real programmers use.

repeat(3, () => swim("fish", 50))

1. 1Add Bubbles

   Create the fish.

   createAnimal("fish")

2. 2The long way

   First write swim three times so you can see what repeat has to do.

3. 3The shortcut

   Now delete those three lines and replace them with one repeat line. Press Run — same result, less typing!

4. 4Cheer

   Add a say line at the end.
