What are best practices for working with references?

When working with references in Perl, following best practices can help you manage memory efficiently and write clean, maintainable code. Here are some key best practices:

  • Use references for complex data structures: References allow you to create complex data structures like arrays of arrays and hashes of hashes.
  • Keep it simple: Limit the number of nested references to enhance readability.
  • Use dereferencing properly: Know when and how to dereference to access the data within your references effectively.
  • Document your code: Add comments to explain your use of references, especially in complex scenarios.
  • Utilize the `Data::Dumper` module: This module can help you visualize complex data structures containing references for debugging purposes.
