Instructions

• Open index.html in the web browser
• Type anything in the input box "Hello JS". It will disappear in on every tick, because the whole "js" div is regenerated on every tick.
• Type anything in the input box "Hello React". It will stay there, because React is smartly only regenerating the paragraph with the timestamp string.
