Deep Dive: Why Abstraction Matters
Abstraction is about creating models that simplify reality:
- Maps - Show roads, ignore trees and buildings
- Variables - "score" abstracts the actual memory location
- Functions - "print()" abstracts complex output operations
- Classes - "Car" abstracts engine, wheels, steering into one concept
Good abstraction hides complexity while keeping essential details. The Tube map is genius abstraction - you don't need geography to plan your journey!
