What Is It?

Associative arrays, also frequently called hashes, are the third major data type in Perl after scalars and arrays. Hashes are named as such because they work very similarly to a common data structure that programmers use in other languages--hash tables. However, hashes in Perl are actually a direct language supported data type.
