The hash function in associative arrays (map) is used to convert the key into an index of the array where the value is stored. This allows for quick finding, adding, and deleting of elements by key with an amortized complexity of about O(1).

Working principle:

• The key passes through a hash function that returns a numeric value (hash).
• Based on this hash, the position in the internal data structure (usually an array) is determined.
• If a collision occurs (different keys produce the same hash), a collision resolution method is used (chaining or open addressing).

In Go, maps are implemented using hash tables, where the hash function ensures a uniform distribution of keys for efficient access.
