A minimalist yet powerful collection of data structures designed for practical use. Features production-ready implementations of linked lists, stacks, queues, and binary search trees with strict type enforcement. The package enforces data consistency across structures while enabling developer-friendly patterns like method chaining. Binary search trees automatically sort content and reject mixed data types, eliminating runtime surprises. Includes comprehensive testing and Node.js + browser support. Built for developers who need reliable data structure implementations without dependencies. Particularly useful for interview preparation, algorithm visualization, and educational purposes.
