@sinonjs/referee is a powerful assertion library, extracted from Sinon.JS. It provides a flexible API for making detailed assertions about values, going beyond simple equality checks. With features like type checking, near equality assertions for numbers, and deep object comparison, Referee helps write expressive and maintainable tests. Its modular design allows selective inclusion of features. It's ideal for unit testing scenarios where precise validation of expected outcomes is critical.
