What is an ECS?

An entity-component-system (ECS) is a software architecture pattern. See ECS ⋅ Wikipedia.
It is often used in the Gaming industry - e.g. Minecraft - and used for high performant data processing.
An ECS provide two strengths:

1. It enables writing highly decoupled code. Data is stored in Components which are assigned to objects - aka Entities - at runtime.
   Code decoupling is accomplished by dividing implementation in pure data structures (Component types) - and code (Systems) to process them.

2. It enables high performant system execution by storing components in continuous memory to leverage CPU caches L1, L2 & L3.
   It improves CPU branch prediction by minimizing conditional branches when processing components in tight loops.
