How it works

The user is asked for the score for the first frame and so on until the game ends when the user has entered the scores for 10 frames. Throughout the game is notified for any bonus scores and bonus games such as Strike, Spare, Perfect Game and Gutter Game.

Notes

To check the scores are following the rules of bowling I use this tool: https://www.bowlinggenius.com/

The rules of bowling can become complex when you start adding the bonuses and the 10th frame.

For the folder structure I asked ChatGPT and searched on google which led me to this: https://stackoverflow.com/questions/5178334/folder-structure-for-a-node-js-project

Readline feature

Used ChatGPT to find out how to use the readline feature and this is also a good resource: https://nodejs.org/api/readline.html
