In what cases is it advisable to use hash tables for data storage?

Hash tables are suitable when you need fast access to data — insert, search, and delete operations are performed in average constant time O(1).

Examples of use cases:

• Caching data for quick access.
• Implementing dictionaries or mappings (e.g., storing settings by name).
• Counting the frequency of elements.
• Fast search by a unique identifier.

However, if ordered traversal of elements is important or if there are frequent collisions, other data structures should be considered.
