What do you mean by a Scala map?

The collection of key-value pairs where the key can retrieve the values present in a map is known as a scala map. The keys, unlike the values in a scala map are unique. There are two types of maps present in scala:

• Mutable
• Immutable

By default, immutable map is supported by scala. To use the mutable map, the programmer needs to import the “scala.collection.mutable”. It is an explicit class. “mutable.map” is the syntax for using the mutable and immutable class in the same program. To access the immutable class, we just have to use the name of the map and it can be accessed.
