5. Limited Compatibility with CPAN modules

Perl programming language has a rich set of modules that can be downloaded from CPAN (Comprehensive Perl Archive Network) for free. However, one of the disadvantages of using Perl is that it has limited compatibility with CPAN modules. Which can create problems when trying to run Perl programs on different systems. A Perl program containing CPAN modules may not run on another system that does not have those modules installed. This can cause compatibility issues and may become a hurdle for programmers who want to share their code with others. To overcome this limitation, programmers must ensure that all the required modules are installed on the system before running their program. Despite this limitation, Perl remains a popular programming language due to its flexibility, simplicity, and efficient text and string manipulation capabilities. Overall, Perl offers several advantages with some limitations that can be overcome with careful planning and execution.

6. Interpretative Nature and Slower Performance

Perl is an interpretative language, which means that it runs slower in comparison with other languages. This can be a drawback when dealing with large programs. Furthermore, untidy and unreadable code can create problems when the code is larger than 200 lines. Although Perl is a versatile language, its interpretative nature can also be seen as a disadvantage. Unlike compiled languages, which are translated into machine code before execution, interpreted languages are executed directly by the computer, resulting in slower processing times. This can be especially problematic when dealing with larger programs that require more complex calculations. Despite these limitations, however, Perl remains a popular programming language due to its rich set of modules and free software, simple syntax, and flexibility. Additionally, Perl has a vast community of developers. Who has contributed to a vast library of modules and extensions that can be used to extend the language’s functionality? Ultimately, the choice to use Perl will depend on the specific needs of the user and the requirements of the project.

7. Untidy and Unreadable Code

Perl language may pose some challenges with its coding style, as it can become untidy and unreadable when used for larger coding tasks.
