Scala Collections

Collections are a set of classes that are used to group multiple elements together. Collections also provide a standard way of processing the elements inside them.

Scala has a very rich Collection API. Scala provides both mutable and immutable Collections.

In this series, we will discuss different Scala Collections and their operators.
