What will I learn?
The JavaScript Design Patterns Course teaches how to build modular applications with clear APIs, employing facades, singletons, factories, and strategy-based storage. You will create Observer and Pub/Sub event systems, develop flexible interfaces, and use testing patterns involving mocks and spies. Gain skills in refactoring for better maintainability, switching storage strategies securely, and extending features with minimal disruption in practical projects.
