Pipesicle

The program we wrote is available on Repl.it at https://repl.it/@tmcl1/BindYourLove#Main.hs

It's also available on github at https://github.com/tmcl/BindYourLove

In this episode, we discuss piping in Elm and Elixir, we discuss currying functions and we also talk a bit about why functions parameters go in different orders between Elm and Elixir, and how that works out in practice.

Tristan tries to read out some code examples. During the discussion on currying, he reads some javascript:

First, the uncurried, natural form:

function (x, y) { return x + y; }

and then, the curried javascript form:

function (x) { return function (y) { return x + y; }; }

Later, in the discussion on function parameter order in Elixir vs Elm, he compares some Elm code in piped and unpiped form with some Elixir code in piped and unpiped form.

First, piped Elm:

getPeople source |> List.filter (hasMinimumAge 20)

Second, unpiped Elm:

let people = getPeople source in List.filter (hasMinimumAge 20) people

Next, piped Elixir:

getPeople source |> Enum.filter(hasMinimumAge 20)

And finally, unpiped Elixir:

people = getPeople source Enum.filter(people, hasMinimumAge 20)
