A great course by Lydia Hallie on Frontend Masters‼️ 👏

I really enjoyed the journey, from the definition of design patterns: “Design patterns are concepts to performantly solve commonly recurring problems in software architecture.”

Lydia Hallie goes through a collection of patterns, indicating the pros and cons for each and presenting scenarios where these could be implemented, accompanied by practical exercises for each lesson.

💡 A great resource for an even deeper dive into patterns
