In elixir the pipe operator |> allows you to pass the result of an expression as the first parameter of another expression.

For example:

list |> reverse

Where reverse is a function

However if the function takes more than 1 parameter, it is recommended to use parentheses to pass the second argument when using the pipe operator.

For example:

list |> take(5)

Where take is a function that takes 2 parameters
