This project provides a collection of JavaScript (ES) value fixtures for use in unit tests. It is designed for JavaScript developers who need reliable, standardized test data when writing test suites for code that manipulates or expects specific ES values. The fixtures simplify test setup by offering pre-defined, consistent examples of common JavaScript types and edge cases.
