Parameters Make Functions Flexible

A function with no inputs always does exactly the same thing. Parameters turn one function into hundreds of possibilities.

1. 1Define hop

   Write hop(name, times) that jumps a given number of times.

   function hop(name, times) {
     for (let i = 0; i < times; i++) {
       jump(name)
       moveForward(name, 20)
     }
   }

2. 2Two animals

   Create a frog and a rabbit.

3. 3Different inputs

   Call hop with different numbers for each animal.
