JOWhy do we even need design patterns? ๐
Code starts simpleโฆ
but as features grow โ it becomes messy ๐ฌ
๐ too many if-else
๐ duplicate logic
๐ hard to modify without breaking things
๐ก Design patterns give a structured way to handle these problems
๐ข Creational
When object creation becomes messy
Example: payment methods (UPI, Card, Wallet)
๐ต Structural
When you want to add behavior without changing existing code
Example: adding logging & authentication to every API call
๐ฃ Behavioral
When system behavior changes based on situation
Example: payment flows, notification systems
๐ง Learn patterns โ write clean, scalable code
