Perl is a dynamic scripting language popular among system administrators and web developers. It is syntactically similar to the C Programming Language, but designed for efficient text processing tasks.

Its powerful string parsing abilities has made it the language of choice on high traffic 6, sites like DuckDuckGo, Booking.com, and Craigslist.

Declare a variable with a dollar sign, then print it to the standard output, and the variable can be easily interpolated into another string.
Variables can be scoped locally with the my keyword or globally to an entire package with the our keyword.
The dollar sign creates a scalar variable, which is a single value like a string or number.
If we the dollar sign to the at symbol, this variable becomes an array.
The index of any item in the array can be accessed with brackets.
Now, name the variable with a percent 7 to get a hash or key value pair.
To access one of its keys, use braces.

In this video, the host discusses the language, praising its dynamic interpreted scripting abilities and its use in high traffic sites like denies.com and beyond. The language is also discussed in its various forms, including Roku, a glue language similar to C, and synergistic. The host also explains its design principles and features, including auto vivification and a lot of technical features, including a command line and a command line extension.
