Chapter 4. Collections and Stream Processing

Now that we have the syntactical basics of Elixir, we can really start to do exciting things. In particular, we can take some of the ideas mentioned in the previous chapter—recursion and pattern matching—to do some really exciting and cool things. For example, we can introduce one of the coolest operators of Elixir, the pipe operator (|>); start doing something called pipeline programming; and borrow an idea from the early days of computing.
