We've learned about how to create and work with list and map literals in very basic ways. Let's take a look into some of the tooling that Elixir provides as core language features, for working with these data structures.

We have a program that starts with a list of objects read from a file. Using the built-in functions available in the Enum and Map modules, filter out "inactive" items (objects where the "active" attribute is not true), and then log a list of object names to the console.

Often we find ourselves looping over something enumerable; mapping values into another list; and potentially filtering out some unwanted items. Comprehensions use a generator and a filter to provide some excellent syntactic sugar for this kind of task.

Take another pass at the previous exercise, and use a comprehension to devise a concise solution.

Elixir's Stream module offers some of the same capabilities that we enjoy in the Enum module, but when working with Streams, computations are performed lazily. This is particularly useful for dealing with huge (or infinitely huge) collections.

We'll round out the course by recapping everything we've learned, and finish with some tips for next steps in your mission to become an ace Elixir developer!
