General Design Principles
DRY, YAGNI, and KISS: The three rules for writing manageable code.
DRY prevents redundancy, YAGNI prevents over-engineering, and KISS prevents unnecessary complexity.
Core Design Challenge
"What are the core habits that prevent code from becoming a mess?"
What You'll Learn:
- ✦Encapsulation: hiding internal data and exposing interface methods
- ✦Abstraction: simplifying complex operations behind clean facades
- ✦Inheritance: promoting code reusability via superclass relationships
- ✦Polymorphism: executing dynamic implementations via shared interfaces
