Modern Android patterns with Kotlin, coroutines, and functional programming.

Kotlin Idioms

Immutability

// ✅ Prefer val over var
val name: String = "John"

// ✅ Read-only collection types (List/Set/Map are read-only, NOT immutable:
// a MutableList held elsewhere can still change behind this reference)
val items: List<Item> = listOf(item1, item2)
