But # either or both could be numbers. In general, the hash in Perl is defined as a collection of items or elements which consists of an unordered key-value pair where the values can be accessed by using the keys specified to each value, and in Perl, hash variables are denoted or preceded by a percent (%) symbol and a single element can be referred by using “$” symbol followed by key and value in the curly braces. Perl stores elements of a hash in such an optimal way that you can look up its values based on keys very fast. With the array, you use indices to access its elements. However, you must use descriptive keys to access hash’s element.
