If / Else: Making Decisions

A fox reaches a river. If it has enough energy it leaps across; if not, it stops for a rest. Code can choose between two paths using if and else.

if (energy > 50) { … } else { … }

1. 1Set the energy

   Store the fox's energy in a variable.

   let energy = 80

2. 2Add the fox

   Create a fox.

3. 3The decision

   If energy is over 50 the fox leaps; otherwise it rests.

4. 4Test both paths

   Change energy to 20 and press Run. A different branch happens!
