What is Unity ECS?

Unity ECS stands for Entity Component System, a data-oriented framework in Unity for writing high-performance, scalable game code. It separates data (components) from behavior (systems) and organizes game objects as entities, allowing efficient processing and better use of modern multi-core processors. Unity ECS is part of Unity's DOTS (Data-Oriented Technology Stack) initiative, designed to help developers build more complex and performant games. This approach can lead to significant improvements in memory management and execution speed compared to traditional object-oriented methods.
