Kotlin Map Functions: The Difference Between mapOf() and mutableMapOf()
n Kotlin, mapOf() and mutableMapOf() are functions used to create immutable and mutable maps, respectively. Maps are collections of key-value pairs where each key maps to a single value. An immutable map, created using mapOf(), cannot be modified after its creation, whereas a mutable map, created using mutableMapOf(), can be updated, adding or removing entries.
Immutable Map:
This is suitable when you need a fixed, read-only collection of key-value pairs.
Mutable Map:
This is suitable for cases where you need to modify the map content at runtime.
This code demonstrates the creation of an immutable map using mapOf() and a mutable map using mutableMapOf(). It initializes both maps with the same key-value pairs. After that, it adds, updates, and removes entries from the mutable map, showcasing the flexibility of mutable maps in contrast to immutable maps.
