function increment(tree, by = 1) {
  tree.apply('counter', nb => nb + by);

function decrement(tree, by = 1) {
  tree.apply('counter', nb => nb - by);
}

      render = createRenderer(document.body, dispatcher);
 
// 4. Creating a counter component

    <div>
      <p>{props.counter}</p>
      <div>
