Generator Functions

What are generator functions?

Generator functions are basically functions that you can pause at some point. You can define a generator function with function*:

function* Generator() {
  // code goes here
}

I like to named my generator functions with a capital, for reasons that will become apparent later, but generally they are named with a lowercase letter.
