+/**

+ * value when its setter is called with no argument.
+ *
+ * @param initialState The initial boolean value
+ * @returns A tuple of the current state and a setter
+ *
+ * ```jsx
+ * const [show, toggleShow] = useToggleState(false)
+ *
+ * return (
+ *   <>
+ *     <button onClick={() => toggleShow()}>
+ *       Toggle
+ *     <button>
+ *
+ *     {show && <strong>Now you can see me</strong>}
