Kotlin filterTo Function

The filterTo function in Kotlin is used to filter elements of a collection based on a given predicate and store the filtered elements in a specified destination collection. This function belongs to the Kotlin standard library and provides a flexible way to filter elements and collect the results in a custom destination.

Kotlin filterNotNull Function

The filterNotNull function in Kotlin is used to filter out all null elements from a collection, returning a new list containing only the non-null elements. This function belongs to the Kotlin standard library and provides a convenient way to ensure that a collection does not contain any null values.

Kotlin filterNot Function

The filterNot function in Kotlin is used to filter elements of a collection based on a given predicate, returning a new list containing only the elements that do not match the specified condition. This function belongs to the Kotlin standard library and provides a convenient way to exclude certain elements from a collection.

Kotlin mapOfNotNull Function

Kotlin does not provide a built-in mapOfNotNull function, but you can achieve the same functionality by filtering out null values and creating a map with non-null entries. This is useful for initializing maps where some values may be null, ensuring that the resulting map contains only non-null entries.

Kotlin List getOrNull Function

The getOrNull function in Kotlin is used to safely retrieve an element from a list by its index. If the index is out of bounds, it returns null instead of throwing an exception. This function belongs to the List class in the Kotlin standard library and provides a way to handle potentially invalid indices gracefully.
