What will I learn?
The JavaScript Design Patterns Course teaches you how to build modular apps with clear APIs, using facades, singletons, factories, and strategy-based storage. You will implement Observer and Pub/Sub event systems, design flexible interfaces, and apply testing patterns with mocks and spies. Learn to refactor for maintainability, switch storage strategies safely, and extend features with minimal impact in real projects.
