Two Kinds Of Elixir Constants

What Do I Mean By 'Constant'?

First it feels appropriate to say that when I say constant I have a definite technical meaning in mind. In a mathematical sense a constant like pi or e is simply a value that's fixed on the number line. In the sense that software developers use the word "constant" we usually mean something which is an extension of the notion of a mathematical constant--a fixed value. It could be a number or a string or even a more complex data structure; the point is that in the course of the normal execution of the binary it won't change.

Here I'm using the term constant to name a value that needs to be referenced in two or more modules in Elixir which none of them will change. The value will be defined in one module and then read from others. There are two reasons to do this approach:

1. It makes the code more readable
2. It keeps the developer from repeating his/her self.
