Lesson Briefing

"The 'Observer' pattern is the soul of reactive programming. When 'System A' changes, 'System B' and 'System C' are notified automatically. This decouples the 'Producer' of data from its 'Consumers'. The 'Strategy' pattern allows you to change the 'Brain' of an object at runtime, which is vital for building flexible AI or data processing engines."
