Answer / sey

both hash table and arrays are data structure, but the way
they store data are different. hash table in some way use
array for its implementations so what makes it a hash table
is the design of hash function that map key(value)to the
hash table. the has function has noting to do with the
actual value(key) except to create O(1) hit to access,
insert or delete item.

When generate a hash table, you don't have to set the
size. When generate an array, the size has to be set.

Hash table can save you space if you don't know how big an
array you may need.
