So, you are saying that this :

    (ns example
      (:require [reagent.core :as r]))

    (def click-count (r/atom 0))

    (defn counting-component []
      [:div
       "The atom " [:code "click-count"] " has value: "
       @click-count ". "
       [:input {:type "button" :value "Click me!"
                :on-click #(swap! click-count inc)}]])

Is better than this :

    import QtQuick.Controls 2.3
    Button {
        property int count: 0
        onClicked: count++
        text: count == 0 
              ? "Click me!" 
              : "The value is : " + count
    }
