ArrayList

expect class ArrayList<E> : MutableList<E> , RandomAccess

actual typealias ArrayList = ArrayList<E>

actual open class ArrayList<E> : AbstractMutableList<E> , MutableList<E> , RandomAccess

Provides a MutableList implementation, which uses a resizable array as its backing storage.

This implementation doesn't provide a way to manage capacity, as backing JS array is resizeable itself. There is no speed advantage to pre-allocating array sizes in JavaScript, so this implementation does not include any of the capacity and "growth increment" concepts.
