Understanding functions and parameters

In this lecture we will dive deeper into functions to really understand how they work. The first step is to understand the difference between variables and functions. While variables are just containers of data, functions are containers of action.

So far we worked with the built in functions but we didn't really dive into what they actually do. In this lecture we'll understand how functions work and discover how parameters work.

Parameters are a fancy name for variables. Not just regular variables but variables that are being sent into a function. You want to send in variables into a function when you want to have customization to inaction. Such as, a running function you would want to tell the function who should run.
