An interface is the names, inputs, and outputs of a piece of code. They are the knobs and handles we use to interact with the code.

Interfaces are defined by three things:

  1. A clear, concise, descriptive name
  2. The input data or arguments
  3. The output data or return value

When building applications, we organize our code with functions and organize our functions into modules or classes. The interface of a module or class are it's functions along with those functions arguments and return values.

It is important to test and document our interfaces. This provides us and our collaborators with a better understanding of how to use the code.
