WebA hash is sometimes referred to as an associative array. Like a scalar or an array variable, a hash variable has its own prefix. A hash variable must begin with a percent sign ( % ). The prefix % looks like key/value pair so remember this trick to name the hash variables. The following example defines a simple hash. Hashing means using some function or algorithm to map object data to some representative integer value. This so-called hash code (or simply hash) can then be used as a way to narrow down our search when looking for the item in the map.
