toggle button

To create a toggle button in Clojure, you can use the :on-click attribute of the :button element to define a function that changes the state of the button when it is clicked. Here's an example:

(ns my-app.core
  (:require [reagent.core :as reagent]))

(defn toggle-button []
  (let [toggle-state (reagent/atom false)]
    [:div
     [:button
      {:on-click #(swap! toggle-state not)}
      (if @toggle-state
        "ON"
        "OFF")]]))

(defn mount-root []
  (reagent/render [toggle-button]
                  (js/document.getElementById "app")))

(mount-root)

In this example, we define a function toggle-button that creates a button element. The :on-click attribute is set to a function that toggles the value of the toggle-state atom using swap!. The text displayed on the button is determined by the value of toggle-state.

To use this toggle button in your application, you can call the mount-root function to render the button component to the DOM. Make sure you have an HTML element with the id "app" where you want the button to be rendered.

This code uses Reagent, a ClojureScript library for building user interfaces. Remember to include the necessary dependencies in your project.clj file if you haven't already.

I hope this helps! Let me know if you have any further questions.
