The (not so) Bad parts

Monolith

Bundle size

Entity–component–system

Entity-component-system (ECS) is an architectural pattern that is mostly used in game development

it is better to compose what an object can do (HAS-A) than extend what it is (IS-A)

Entities are container objects into which components can be attached. Entities are the base of all objects in the scene.

Components are reusable modules or data containers that can be attached to entities to provide appearance, behavior, and/or functionality.

Systems provide global scope, management, and services for classes of components.

<a-entity geometry="primitive: sphere; radius: 1.5"
          light="type: point; color: white; intensity: 2"
          material="color: white; shader: flat; src: glow.jpg"
          position="0 0 -5"></a-entity>
