Manipulate arrays and hashes like a pro with this Perl function guide

Overview: This document explores some of the most useful Perl functions for manipulating arrays and hashes, with brief explanations of how each one works and when it should be used.

This download lists several these Perl data structure functions in an easy to read quick reference table. Besides listing the function, showing the syntax, and explaining how and when to use it, each function is also shown in an example code snippet. Some of the functions explained in this download include:

• scalar(@arr)
• pop(@arr)
• delete $hash{$key}
• sort(@arr)
