Workshop 4

Arrays

Arrays can also be created using a key/value pair combination. These are often referred to as associative arrays or hashes. In a hash each value is associated with a unique key. Unlike list arrays that use a number as an index value, associative arrays use any value. The easiest way to comprehend how a hash works is to think of it as a table. In the following table the state name serves to role as key and the city is the value.

State (key)	City (value)
Victoria	Melbourne
NSW	Sydney
South Australia	Adelaide
Queensland	Brisbane
Tasmania	Hobart
