Why are parameters useful?

• They allow us to tailor functions to be used in multiple situations

• They allow us to change the order of commands in a function

• They give us the ability to use variables in loops

• They allow the user to give input

Why do we use if statements?

• To tell Tracy to stop our code if there’s an error

• To have Tracy make decisions based on conditional statements

• To tell Tracy to do something if we run our code

• To have Tracy complete one function at a time
