The 'takeLast' function is useful when you want to obtain a specified number of elements from the end of a collection. This can be particularly handy in scenarios where you're interested in the most recent items, such as the latest messages in a chat application or the most recent transactions in a financial app.
val transactions = listOf("Deposit", "Withdrawal", "Transfer", "Deposit", "Withdrawal")
val recentTransactions = transactions.takeLast(3)
println(recentTransactions) // Output: [Transfer, Deposit, Withdrawal]
