Okay... that's not saying much though? Why even mention it? I don't know anything about Elm but this looks like a blog post about JS, not Elm, but it's talking about Elm right from the start as if that's an important distinction to make here.

It's like those recipe blogs that have to give you their life story before telling you how to make a meatball. Just get to the damn point and skip the bullshit, please.
