A TypeScript Node.js application that accurately calculates the total score of a bowling game from a frame-based input.
The Bowling Score Calculator parses and evaluates a ten-frame bowling game, correctly scoring strikes, spares, and open frames, including special rules for the 10th frame. It supports a test suite for reliable development and maintains clean code with linting and formatting tools.
- Converts symbolic bowling input (
X,/,-, etc.) to numerical scores. - Correctly identifies and scores strikes, spares, regular, and gutter frames.
- Handles bonus throws in the 10th frame.
- Modular design with a clear separation of logic.
- Includes unit tests for all key scoring logic.
- ESLint and Prettier for code quality and consistency.
