  • The top example is simply function composition. E is defined as: func(e *Element, modifiers ...func(*Element)*Element) *Element
    So Children is just a mere Element modifier function like CSS and Listen and whatnot.

  • The middle example does not directly use function composition. Children elements are passed as argument (variadically).
    The signature of E has become func(*Element, modifiers []func(e *Element)*Element, children ...*Element) *Element

  • the bottom example is just to show how it would look if the app was designed imperatively only.
