This is an application simulating a gameshow where a user tries to pick a briefcase which contains a prize from a selection of identical looking briefcases.
/src/index.js contains the logic for the game show, while /src/spec/index.js contains the "simulation code" which runs the game thousands of times to come up with some recommendations for marketing.
This is a pretty awesome prototype!
Benefits include:
- Modular architecture avoids mutation, allows for easy testing
- Application actually works - it recommends ways for the prize department to save money
- Logic and spec code nicely separated
- Fast! Simulates 30,000 games in 100ms or less.
- Customizable - number of briefcases can be changed to any amount. Code also supports (with some light additions) the increasing of briefcase reveal steps, having more than one briefcase with a prize, etc.
- Clone the repository
- Run
npm install(make sure you have Node installed) - Run
npm test
Output of the simulation should look like this:
Final analysis (3 briefcases):
Win rate when you do not switch choice: 34%,
Win rate when you do switch : 66%.
Switching choices increases contestant's chance of winning by 31%.
Final analysis (4 briefcases):
Win rate when you do not switch choice: 25%,
Win rate when you do switch : 37%.
Switching choices increases contestant's chance of winning by 11%.
