So far, we haven't seen much more than tiny snippets, demonstrating a fraction of the syntax of Elixir. Now we are going to go into more detail and look at some more in-depth examples.
We will start with what may be considered a functional language's real "hello world", the map function.
Note that this example will use some concepts that we are going to go into more detail in the next few chapters.
The map function essentially takes a function and a list, and applies the function to each element in the list. Ideally, the application of one element in the list does not depend or effect any other application of any other element.
