Map

A map is defined as the name of a higher-order function in most of the programming languages that applies a given function to each element of a functor, such as a list, and returns a list of results in the same order. A map is also called the collection of values based on a key, i.e. a key and value pair. A map has its own set of keys. Duplicate keys are not permitted in the Map, although duplicate values are permitted. Because a Map cannot be navigated, it must be converted to a Set using the keySet() or entrySet() methods. For key-value association mapping, such as dictionaries, maps are ideal.
