Introduction

Maps are a collection of key-value pairs that a user can use to store some data and retrieve it with a key. In some languages, these are called dictionaries (Python) or hashes (Perl). In contrast to an array/slice, finding an entry in a map requires a single lookup versus iterating over the entire slice comparing values. With a large set of items, this can give us significant time savings.
