Dictionary
A Dictionary is a data structure that stores key–value pairs, allowing fast lookup, insertion and deletion using unique keys. Unlike lists or arrays, a dictionary does not rely on indexing; instead, keys provide direct access to values. Dictionaries are widely used for configurations, mappings, caching and structured data storage due to their efficiency and flexibility.
