SanderMertens/ecs-faq: Frequently asked questions about Entity Component Systems

A good starting point to dive into ECS. There is a strong emphasis on the performance of ECS, and while it is mentioned, it is not stated clearly that ECS is not always about performance. Primarily, it is an architectural approach. With the right design — both in terms of framework and game design — it can significantly benefit performance, but this is not guaranteed by default.
