Summary

This chapter covered a lot of topics, such as variables, data types, functions, operators, code blocks, scope, and code flow. All of these concepts are the basic building blocks of Lua. These concepts are very important to programming, so you may need to come back to this chapter.

In Chapter 3, Tables and Objects, we will cover tables and objects. An alternate syntax of the for loop will be covered that can be used to easily iterate over tables or arrays.
