• Set of guidelines by Robert C. Martin AKA Uncle Bob
• Helps you oriented your code towards future use, not just immediate needs
• Modular, flexible and independent code :)

Why?

1. Too much dependency (spaghetti code)
2. Rigidity: changes affects other parts
3. Fragility: breaks in unrelated places
4. Immobility: can’t reuse code outside the original context

S - Single responsibility

• A class should have only one reason to change
• Doesn’t mean have to be one function
• If part needs to change for different reasons maybe need to refactor

O - Open-closed

• Be able to extend a class without modifying.

L - Liskov substitution

• Derived classes must be substituable for their base classes

I - Interface segregation

• Make fine-grained interfaces with specific methods

D - Dependency inversion

• Depend on abstractions, not on concretions
• Take advantage of interfaces
• If you’re creating and instance of a class inside of another maybe you need to rethink this, or pass the instance into
