Your task is to write a function for calculating the score of a 10 pin bowling game. The input for this function will be an array of objects, and each object represents one frame. The objects can have any properties and values you see fit. Figuring out your input's data structure is part of the challenge.
- Create a Git Repository for this challenge
- commit often and have your commit messages be descriptive
- Write tests for your function using the Mocha and Chai.
- Provide test for all cases. Handle unexpected inputs, invalid arguments, etc.
A game consists of 10 frames. In each frame the player rolls 1 or 2 balls, except for the 10th frame, where the player rolls 2 or 3 balls. The total score is the sum of your scores for the 10 frames
- If you knock down fewer than 10 pins with 2 balls, your frame score is the number of pins knocked down
- If you knock down all 10 pins with 2 balls (spare), you score the amount of pins knocked down plus a bonus - amount of pins knocked down with the next ball
- If you knock down all 10 pins with 1 ball (strike), you score the amount of pins knocked down plus a bonus - amount of pins knocked down with the next 2 balls
- If the last frame is a spare, player rolls 1 bonus ball.
- If the last frame is a strike, player rolls 2 bonus balls.
These bonus balls on 10th frame are only counted as a bonus to the respective spare or strike.
You may assume that the input is always valid. This means:
input list length is correct number of pins knocked out per roll is valid
