Speaking of writing javascript instead of JSX, I'm a big fan of the hyperscript approach:

      var ListComponent = () => {
        let count = 0, selected = null
        return {
          view: ({attrs: {items}}) =>
            m("div", [
              m("p", "Clicked: " + count + " times"),
              m("ul", items.map(item =>
                m("li", {
                  onclick: () => { count++; selected = item },
                  style: {cursor: "pointer", color: item === selected ? "blue" : "black"}
                }, item)
              )),
              selected && m("p", "Selected: " + selected)
            ])
        }
      }
