This chapter explores the use of a variety of containers. You learned that variables, arrays, and hashes have the commonality of being able to store data, but they do it in different ways. You learned that different types of data can be stored in these containers. These types of data include numbers, strings, and objects.

This chapter explored that variables are best used for the storage of single-dimensional datasets. These datasets can contain strings but also include mathematical equations that PowerShell has the ability to inherently calculate. You also now know that arrays are primarily used in situations where you want to store more than one set of data. You are able to navigate, add, and remove values in the array based off of a starting value of 0. Last, you learned that hashes are best used while correlating data from one value to another. You are able to add, remove, and search data contained in the hash tables with the use of simple commands. In the next chapter, you will learn techniques to perform data parsing and manipulation by leveraging variables and arrays.
