Refactor: Simplify Branching
Reduce conditional complexity for better readability.
Techniques
1. Guard Clauses (Early Return)
Replace deep nesting with flat guards.
2. Replace Conditionals with Polymorphism
Use protocol dispatch instead of type checking.
3. Replace Nested Conditionals with Table
Use lookup tables for multi-dimensional conditions.
4. Decompose Compound Conditionals
Extract complex conditions to named variables or methods.
5. Replace Flag Arguments
Create separate methods instead of boolean flags.
Warning Signs
- Nesting > 3 levels deep
- More than 3 else-if branches
- Switch with > 5 cases
- Condition spans multiple lines
