fun <T> emptyList(): List<T>
(source)

Returns an empty read-only list. The returned list is serializable (JVM).

import kotlin.test.*

fun main(args: Array<String>) {
//sampleStart
val list = listOf<String>()
println("list.isEmpty() is ${list.isEmpty()}") // true

// another way to create an empty list,
// type parameter is inferred from the expected type
val other: List<Int> = emptyList()

// Empty lists are equal

println("list == other is ${list == other}") // true
println(list) // []
// list[0] //  will fail
//sampleEnd
}
