Array

• You would use a List data type to store an immutable collection of objects when you don't know how many members will be in the collection. Lists are indexed collections of elements that can be accessed by their position in the list, and they are commonly used to store collections of items that need to be processed in order. Additionally, Lists are immutable, which means that their elements cannot be modified once they have been created, making them ideal for use cases where data integrity is important.
