Sequences vs Collections
When each wins.
Sequences vs Collections
Both sequences and collections offer the same functional operations, but they evaluate differently. Knowing when each wins helps you write efficient, readable code.
Eager Collections Recap
Collections are eager: every operation processes all elements and produces a new collection immediately. This is simple and fast for small data.
fun main() {
val result = listOf(1, 2, 3).map { it + 1 }.filter { it > 2 }
println(result)
