Arrays a kind of data structure that can store a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type. It is used to represent multiple data items of the same type by using only a single name. Arrays are more efficient and beneficial when compared to linked lists and hash tables. Faster and can be utilized anywhere. Store data of similar data types together and can be used anywhere in the code.
