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)

• Sorting lists

• Searching lists

• Modifying list contents

• Processing all the elements of a list

• Various string manipulations: reverse, finding substrings, extracting substrings
