Observer pattern lab

Getting started

• Fork and clone repo
• Install dependencies: yarn install
• cd into project directory
• Run tests: yarn test

Tasks

• Fix failing test in FootballGame.test.js
• Add Fan class. A fan should have a team that they support (this can be just a string) and they should be able to react() with a 'yay!' if their team scores, and 'boo!' if another team scores
• A Fan is a Spectator. A Report also is a Spectator. Create a Spectator class and make fans
• As with all football games, spectators (i.e. fans and reporters) can arrive late. Create a method to add a late spectator to a football game
• Now, fans and reporters should react when a team scores in a football game. Update .teamScored() to make all spectators react
