As we begin writing algorithms, let's stop and discuss how to organize our code into reusable units called functions.

This lesson covers our last core computer capability: the ability to repeat something multiple times, very quickly.

Let's learn about our first data structure: arrays, which put data values in order.

One of the things that makes computers so powerful is their ability to make decisions. We'll explore that capability in our programs in this lesson.

Our journey continues as we examine how we can manipulate the data stored by variables in our programs.

Let's begin our journey in computer science by presenting two of the basic building blocks of computer programs: variables and data types.
