Modules allow you to re-use your code and data.
- [Voiceover] Modules are collections of code…that you may use along with your script.…Modules may contain functions, data,…or object-oriented classes.…Many modules are available on CPAN,…the Comprehensive Perl Archive Network.…CPAN is a very popular repository for Perl modules.…Modules are an excellent way to leverage your code…or a code from others to make your coding projects…easier and more efficient.…Modules may be object-oriented or procedural.…
I strongly recommend that you stick with object-oriented…modules as much as possible.…They're much easier to integrate into your code…and they are less likely to pollute your name space.…Modules may be code, data, or both.…Sometimes we don't think of data only modules…but they do exist.…For example, I have a module on CPAN…which is just a list of country codes and state codes.…Modules make it easy to reuse your code and data.…This allows you to put more effort into writing good code…that you can then reuse for many purposes.…
Watch to learn the details of the Perl syntax, from variables, conditionals, loops, and data structures to regular expressions, functions, and references.
