Just a stupidly fast Entity Component System

-   [Entity Relationships](https://ajmmertens.medium.com/building-games-in-ecs-with-entity-relationships-657275ba2c6c) as first class citizens
-   Iterate 800,000 entities at 60 frames per second
-   Type-safe [Luau](https://luau-lang.org/) API
-   Zero-dependency package
-   Optimized for column-major operations
-   Cache friendly [archetype/SoA](https://ajmmertens.medium.com/building-an-ecs-2-archetypes-and-vectorization-fe21690805f9) storage
-   Rigorously [unit tested](https://github.com/Ukendio/jecs/actions/workflows/unit-testing.yaml) for stability

### Get Started

- examples:
  	These are larger programs that showcase real use cases and can help you understand how everything fits together.
