Using the 'filterIsInstance' Function for Type-Safe Filtering

The 'filterIsInstance' function is a powerful tool in Kotlin that allows you to filter collections based on a specific type. This is particularly useful when dealing with collections that may contain mixed types, as it ensures type safety and reduces the need for explicit type checks or casts.

val mixedList: List = listOf("String", 123, 45.67, true, "Another String")

val stringList: List = mixedList.filterIsInstance()

println(stringList) // Output: [String, Another String]
