An immutable List is an eager sequence of elements. Its immutability makes it suitable for concurrent programming.
A List is composed of a head element and a tail List.
There are two implementations of the List interface:
- List.Nil, which represents the empty List.
- List.Cons, which represents a List containing one or more elements.
A List is a Stack in the sense that it stores elements allowing a last-in-first-out (LIFO) retrieval.
Stack API:
Methods to obtain a List:
```
 
 // factory methods
 List.empty() // = List.of() = Nil.instance()
 List.of(x) // = new Cons<>(x, Nil.instance())
 List.of(Object...) // e.g. List.of(1, 2, 3)
 List.ofAll(Iterable) // e.g. List.ofAll(Stream.of(1, 2, 3)) = 1, 2, 3
 List.ofAll(<primitive array>) // e.g. List.of(new int[] {1, 2, 3}) = 1, 2, 3

 // int sequences
 List.range(0, 3) // = 0, 1, 2
 List.rangeClosed(0, 3) // = 0, 1, 2, 3
 
 
```
Note: A List is primarily a Seq and extends Stack for technical reasons (so Stack does not need to wrap List).
If operating on a List, please prefer
- prepend(Object) over push(Object)
- prependAll(Iterable) over pushAll(Iterable)
- tail() over pop()
- tailOption() over popOption()
Factory method applications:
```
 
 List<Integer> s1 = List.of(1);
 List<Integer> s2 = List.of(1, 2, 3);
 // = List.of(new Integer[] {1, 2, 3});

 List<int[]> s3 = List.ofAll(1, 2, 3);
 List<List<Integer>> s4 = List.ofAll(List.of(1, 2, 3));

 List<Integer> s5 = List.ofAll(1, 2, 3);
 List<Integer> s6 = List.ofAll(List.of(1, 2, 3));

 // cuckoo's egg
 List<Integer[]> s7 = List.<Integer[]> of(new Integer[] {1, 2, 3});
 
 
```
Example: Converting a String to digits
```
 
 // = List(1, 2, 3)
 List.of("123".toCharArray()).map(c -> Character.digit(c, 10))
 
 
```

@GwtIncompatible
default java.util.List<T> asJava()
```
 Description copied from interface: Seq
 Returns an immutable List view of this Seq. Any attempt to modify the view (e.g., via mutator methods) will throw UnsupportedOperationException at runtime.
 This is a view, not a copy. Compared to conversion methods like toJava*():
 
 Creating the view is O(1) (constant time), whereas conversions take O(n), with n = collection size.
 
 Operations on the view have the same performance characteristics as the underlying persistent Vavr collection, while converted collections behave like standard Java collections.
 
 Note: the immutable Java list view throws UnsupportedOperationException before checking method arguments, which may differ from standard Java behavior.
 Specified by:
 
 asJava in interface Seq<T>
 
 Returns:
 
 an immutable List view of this sequence
 - asJava

default java.util.List<T> asJavaMutable()
```
 Description copied from interface: Seq
 
 Returns a mutable List view of this Seq. All standard mutator methods of the List interface are supported and modify the underlying view.
 Unlike Seq.asJava(), this view allows modifications, but the performance characteristics correspond to the underlying persistent Vavr collection.
 
 Specified by:
 
 asJavaMutable in interface Seq<T>
 
 Returns:
 
 a mutable List view of this sequence
 
 See Also:
 
 Seq.asJava()

 Description copied from interface: Seq
 Creates a mutable List view of this Seq and passes it to the given action.
 The view supports all standard mutator methods. The result of the action determines what is returned:
 
 If only read operations are performed, this instance is returned.
 
 If any write operations are performed, a new Seq reflecting those changes is returned.
 Specified by:
 
 asJavaMutable in interface LinearSeq<T>
 
 Specified by:
 
 asJavaMutable in interface Seq<T>
 
 Parameters:
 
 action - a side-effecting operation that receives a mutable java.util.List view

 For each element in iteration order, the function is first tested:
 partialFunction.isDefinedAt(element)
 If true, the element is mapped to type R:
 R newElement = partialFunction.apply(element)
 
 Note: If this Traversable is ordered (i.e., extends Ordered), the caller must ensure that the resulting elements are comparable (i.e., implement Comparable).
 Specified by:
 
 collect in interface LinearSeq<T>
 
 Specified by:
 
 collect in interface Seq<T>
 
 Specified by:

 Specified by:
 
 zipAll in interface Seq<T>
 
 Specified by:
 
 zipAll in interface Traversable<T>
 
 Type Parameters:
 
 U - the type of elements in the second half of each pair
 
 Parameters:
 
 that - an Iterable providing the second element of each pair
 
 thisElem - the element used to fill missing values if this Traversable is shorter than that
 
 thatElem - the element used to fill missing values if that is shorter than this Traversable
 
 Returns:
 
 a new Traversable containing pairs of elements, including fillers as needed
 - zipWithIndex
```
default List<Tuple2<T,java.lang.Integer>> zipWithIndex()
```
 Description copied from interface: Traversable
 
 Zips this Traversable with its indices, starting at 0.

 Specified by:
 
 zipWithIndex in interface Traversable<T>
 
 Returns:
 
 a new Traversable containing each element paired with its index
 - zipWithIndex
```
default  List zipWithIndex(@NonNull java.util.function.BiFunction<? super T,? super java.lang.Integer,? extends U> mapper)
```
 Description copied from interface: Traversable
 
 Zips this Traversable with its indices and maps the resulting pairs using the provided mapper.
