The 'takeWhile' function allows you to take elements from a collection until a specified condition is no longer met. This is particularly useful when you want to process a collection while certain criteria hold true, such as filtering a list of items based on a specific condition.
val numbers = listOf(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
val takenNumbers = numbers.takeWhile { it < 5 }
// takenNumbers will be [1, 2, 3, 4]
