The 'takeLast' function is useful when you want to retrieve a specified number of elements from the end of a collection. This is particularly handy in scenarios where you're interested in the most recent entries, like fetching the latest messages in a chat application or the most recent transactions in a financial app.
val messages = listOf("Hello", "How are you?", "I'm fine, thanks!", "What about you?", "See you soon!") val lastThreeMessages = messages.takeLast(3) println(lastThreeMessages) // Output: [I'm fine, thanks!, What about you?, See you soon!]
