Performance Optimization Kotlin

Reviewer Prompt

Choose direct, efficient methods over approaches that require additional parsing, conversion, or processing steps. This reduces computational overhead and improves performance by eliminating intermediate operations.

When equivalent alternatives exist, prefer:

  • Direct constructors over string parsing (e.g., Color.rgb(11, 6, 0) instead of parsing hex strings)
  • Native method calls over wrapper methods that add conversion layers
  • Conditional execution over forced operations (check if work is needed before performing expensive operations)

Example from code reviews:

// Avoid: String parsing with conversion overhead
val color = if (isDarkMode) "#0b0600" else "#f3f8ff"

// Prefer: Direct constructor
val color = if (isDarkMode) Color.rgb(11, 6, 0) else Color.rgb(243, 248, 255)

This principle applies to any situation where you can eliminate intermediate processing steps, type conversions, or unnecessary method calls that don’t add functional value but consume computational resources.
