• Types are declared with : and not ::, and the consing operator conversely is :: instead of :
• No where clauses, only let/in
• The standard style is different, check http://elm-lang.org/docs/style-guide for reference
• Multiline strings are a thing with """
• Haskell's data corresponds to type in Elm, and also, Haskell's type corresponds to Elm's type alias
• ($) is (<|), but you don't use it all that much – Elm people like the flipped operator (|>) which lets you build something that reads like a pipeline
• Related: Backticks will likely die soon in favour of functions that have an argument order that lends itself to pipelining with (|>)
• Also, (.) is (<<), and a flipped version (>>) exists, but I don't see it used that much either
• (>>=) is not an available operator and would not be polymorphic (no typeclasses, see below), and is instead commonly named SomeType.andThen – e.g. Maybe.andThen : Maybe a -> (a -> Maybe b) -> Maybe b
