Scala Collections
Data structures are an important aspect of Scala. In Scala, these data structures or collections can range from mutable to immutable. Some of these collections are similar to ones in Java such as arrays and maps or Python such as lists and tuples. In this stage we will learn when to use one collection type versus another and how to implement them.
