Fetch New Data Based on Conditions

Each time we eat correctly guess the word, we want to grab a new word to restart our game. This sets up a scenario where we want the getWord broadcaster to make another fetch request when the input box has all of the letters contained in the current word. We can do this by using an operator that will send a value of done if conditions are met and another operator that will tell the broadcaster to repeat when it receives a value of done.
