Pipe operator used before it's introduced about elixirschool HOT 7 CLOSED

Personally (and as someone who is not familiar with Elixir) it seems like a fairly important part of the language's syntax. Perhaps something could be mentioned (as to the effect of option 1) in the first chapter?

From the Pipe Operator page:
"The pipe operator |> passes the result of an expression as the first parameter of another expression."

This seems like a fairly simple and intuitive explanation that could be included, perhaps then reference there is more detail in the dedicated chapter to it.

Done, thank you again @allefgomes!

@allefgomes we should backport this change to the other languages. Would you like to do that? If not I'm happy to do so.

Cheers @allefgomes

Yeah! You are right.
I saw that in guards session the pipe operator appear and don't have a previews explanation about it.

The sessions that use pipe operator are:
Guards
Default Arguments

I think that we have two options:

1. We can put a simple signification like "The pipe operator |> is to send the result of function A to function B as the first argument. You will understood more about pipe operator in the next lesson" .
2. The Guards and Default Arguments sessions can be after introduction of pipe operator.
