?? What Are Value Classes?
Value classes are a powerful feature in Kotlin that allows you to wrap a single value (like a Double or String) in a lightweight and type-safe class. They are:
?? Lightweight and concise
?? Optimized for performance
?? Designed to improve type safety
?? Why Should You Use Them?
1?? Type Safety: Avoid mixing up similar values like Meter and Kilogram.
2?? Performance Boost: The compiler avoids object allocations, making your code faster.
3?? Cleaner Code: Use meaningful abstractions instead of generic primitives.
??? Example Use Case
Imagine calculating force using Kilogram and Meter. By using value classes, you ensure:
?? No accidental mixing of types
?? Efficient performance without unnecessary object creation
?? Clear and maintainable code
For example, defining types like Kilogram and Meter ensures the compiler catches errors, like passing Meter where Kilogram is expected.
