Day 8. Manipulating Lists and Strings
We'll start Week 2 with a hodgepodge of things; in today's lesson, we'll look more closely at lists, arrays, hashes, and strings, and the sorts of things you can do to manipulate the data they contain. A lot of what you'll learn about today uses many of Perl's built-in functions, but these functions are useful to have in your repertoire as you learn more about the language itself.
Today we'll explore
Creating array and hash slices (smaller portions of other arrays and hashes)
Modifying list contents
Processing all the elements of a list
Various string manipulations: reverse, finding substrings, extracting substrings
