Perl is one of the most popular text processing languages in the world. It allows you to create extremely efficient text parsers for all sorts of applications.

This interactive course will help you get up to speed on Perl, starting off with basic concepts like loops, strings, and arrays. You'll build your way up to more complex topics like data structures and packages.

No background knowledge is needed. Anyone willing to understand the principles and syntax of Perl to use it in the future will find this course useful.

## What are variable Variables?
Using Perl, we can access data through dynamic variable names. The name of a variable can be stored in another variable, allowing it to be accessed dynamically. Such variables are known as *variable* variables.

To turn a variable into a *variable* variable, you put an extra `$` sign in front of your variable. This method is illustrated in the following figure:
