2. The primary directive Managing complexity is the most important technical topic in software development. In my view, it’s so important that Software’s Primary Technical Imperative has to be managing complexity - Steve Mcconnell, Code Complete
3. Areas of optimization - Package level - Class level - Routine level
4. Package level - Microservices - An application is a set of collaborating services each service implementing a set of related functions - E.g OAuth for authorization, S3 for storage, Google Cloud SQL for data - Hexagonal design - Application only interacts with outside services via adapters - Component based architecture - Application made of components - Buy don’t build
5. SOLID | Class level - Single Responsibility - Open/Closed principle - Liscov substitution - Interface segregation principle - Dependency inversion
6. Design patterns | Class level - A pattern language is an interconnected set of solutions to common problems in a specific domain - Creational patterns: Singleton, Factory - Behavioral patterns: Chain of responsibility, Commander - Structural patterns: Adapter, Decorator
7. Scope of routines | Function design - Argument length: Monadic, Dyadic, Triadic - Do one thing only - Eliminate flags - No side effects - Command query separation
8. Structured Programming | Function design Every function, and every block within a function, should have one entry and one exit - Edsger Dijkstra, Structured Programming The principles - Only one return per function - No break - No continue
