In a hash table, an array is typically used to store the key-value pairs. The keys are hashed to index locations in the array using a hash function. This allows for efficient retrieval and storage of data, as the key can be used to directly access the corresponding value in the array. Arrays provide constant-time access to elements based on their index, making them a suitable data structure for implementing hash tables.
