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 is a `do-while` loop?

The **do..while** loop is nearly identical to the `while` loop, but instead of checking the *conditional* statement before the loop starts, the **do...while** loop checks the *conditional* statement **after** the *first* run, before moving onto another iteration.

The *syntax* is as follows:
