When should you prefer writing a module (Makefile

When to prefer writing a module in Perl largely depends on the complexity and reusability of your code. If you find yourself repeating similar blocks of code or if your script is growing too large, it's often a good idea to extract that functionality into a module. This enhances maintainability, promotes code reuse, and abstracts functionality for clarity.

Modules allow you to package related functions and variables together, making it easier to maintain and distribute your code. Using modules can also facilitate testing and debugging, as you can isolate functionalities and verify them independently.

Here are some scenarios where writing a module is preferable:

• Your code has repeated functionality.
• You want to share your code with others.
• You need to maintain a clean codebase.
• Your script is getting too big, making it difficult to manage.
