A function with no parameters that prints how many times it’s
been called. Hint: define a variable outside of the function to
keep track of the number of calls, like we did in the “Side
Effects” section on page 77.

let a = 0
let b = 0

A function that takes a number from 0 to 5 and returns the
English word for that number. For example, 1 should return "one".

strings.
