Scala & Spark-Master Big Data with Scala and Spark - Overview of Maps

The video introduces maps as a data structure in Scala, explaining that they consist of key-value pairs where keys must be unique. It distinguishes between mutable and immutable maps, noting that Scala provides immutable maps by default. However, the focus is on mutable maps to allow for manipulation and learning. The video promises further hands-on practice in subsequent videos.
