Here's a cheat sheet outlining some popular design patterns, their pros and cons, and guidance on when to use them:

1. Singleton Pattern:

   • Pros: Ensures only one instance of a class exists, provides a global point of access.
   • Cons: Can introduce tight coupling and make unit testing difficult.
   • Use when: You need to limit the number of instances of a class, such as for managing shared resources or global configurations.

2. Factory Pattern:

   • Pros: Provides a centralized place to create objects, encapsulates object creation logic.

• Cons: Can become complex as the number of product types increases.
