General convenience functions.
byKey : (a -> b) -> b -> a -> Basics.Bool
Create a predicate that matches on a specific extracted value.
> let alice = { id = 1, name = "Alice" }
| bob = { id = 2, name = "Bob" }
| users =
| in List.filter (byKey .id 2) users
[{ id = 2, name = "Bob" }]
flip : (a -> b -> c) -> b -> a -> c
Change the order of the arguments of a two argument function.
> flip (++) "Hello" "World"
"WorldHello" : String
unless : Basics.Bool -> a -> a -> a
Negated, functional if-then-else.
Checks a condition and returns the respective value.
Allows writing more natural conditional atttributes, elements, etc:
div [] [ unless isLoggedIn (text "not logged in") (a [] [ text "logout" ]) ]
