Look inside

As a TypeScript developer, you’ve recently created a high-quality test suite as part of your company’s goal of adding functionality to its system. Now, using test-driven development (TDD) techniques, it’s time to analyze new requirements, reconcile them with what is currently documented by your test suite, and use the test-first technique to ensure changes to your library are justified, specified, and protected by tests.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
