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.

## Adding elements at the start using `unshift()`

One or multiple elements can be added at the start of the array using the `unshift()` subroutine.



>`unshift()` prepends passed elements at the front of an array. Note that the list of elements is
prepended as a whole so that the prepended elements stay in the same order. All numerical array keys
will be modified to start counting from 0.
