Arrays of data is one of the first things we learn about as programmers. Collections of information are a fundamental building block of most programming languages.

JavaScript is no exception. In this series, we will explore JavaScript (es6) array methods. We will slice, join, map, and reduce our way to better understanding of the powerful array methods that modern JavaScript delivers.
