This parser library was developed to safely extract transcription and caption data from the Beey's proprietary file format, replacing older, less maintainable code. The goal was to create a standalone library that adheres to best practices, ensuring robustness, maintainability, and reliability. To enhance its stability, I implemented comprehensive unit tests covering most of the library's functionality, allowing me to catch potential bugs and maintain long-term reliability.

Through this project, I learned a lot about the importance of good design and testability. While experimenting with different parsers as the library’s foundation, the code evolved significantly, yet its functionality remained intact thanks to the extensive tests written with Mocha and Chai.
