Description: A mutable map in Kotlin is a data structure that allows storing key-value pairs, where keys are unique and are used to access associated values. Unlike an immutable map, which cannot be modified once created, a mutable map allows operations such as adding, removing, or updating elements after its creation. This flexibility makes it a valuable tool for handling collections of data that may change over time. Mutable maps in Kotlin are implemented through the ‘MutableMap’ interface, which extends the ‘Map’ interface. This interface provides specific methods for modifying the content of the map, such as ‘put’, ‘remove’, and ‘clear’. Additionally, mutable maps can be initialized with default values, making them easy to use in various applications. The ability to modify a map after its creation is particularly useful in situations where data is dynamic, such as in applications requiring real-time updates or in state management for interactive applications. In summary, a mutable map is an essential tool in Kotlin for the efficient manipulation of data collections that require frequent changes.
