Rails-Oriented Programming

Elixir allows you to pass an anonymous function as an argument and a pipeline. The other design is called railway oriented programming. And yeah, because if we work with this part of principle, we can reuse function call. It helps to read a function called a specification and understand what is going on. But they also have a function called tap, tap will allow you to take. So whatever you pass in is also what you pass out, but then you can do stuff with it.
