Explain the 'KISS' principle.
Updated Apr 28, 2026
Short answer
KISS stands for 'Keep It Simple, Stupid,' advocating for simplicity in design over complexity.
Deep explanation
Junior-level architecture is about mastering fundamental code organization. Principles like SOLID (Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion) provide the toolkit for writing code that doesn't rot. At this stage, understanding that 'good' code is code that is easy to change is paramount.
Real-world example
A simple blog application where the data access, business logic, and UI are kept in separate folders/layers.
Common mistakes
