- Especially, compare to another language they give best and efficient features.
- At the same time, its support the Object orientated Programing’s in Networking Trends.
- In reality, Perl interchange with embedded into other systems in Networking Trends.
- Perl Database Integration Interface DBI Supports third-party access.
Data types
In Perl Language, Perl contains three basic Data types like Scalar, Arrays, and Hashes.
Scalar: Scalar denotes as a Symbol of “$.” At the same time, it is contains either String, a number of references. A Reference is to identify the address of the variables.
Arrays: Important to realize, arrays denote as a Symbol of “@.” List of scalars that access with a numeric index.
Hashes: In fact, hashes denote as a Symbol of “%.” In fact, the hashes of key/value pairs that you access.

Creating Variables: In Perl variable avoid reserving memory space. The “=” Symbol is used to assign a value to variables automatically.
Scalar Variables: In order to, it’s a single unit of data. It may contain integer number. floating point, a character, a string, a paragraph, or an entire web page.
