Lessons > 8. Modules and Variable Scope

In today’s pre-recorded lectures, we are going to go over:

1. Modules: a way of organizing and reusing code, and
2. Variable scope: what parts of memory can your program access at any given time?

In live lecture, we will review the diamond exercise and make sure you feel confident with variable scope and the idea of “modules.”
