Stupid Simple React

// 1. Add the script
<script src="https://ssreact.com/min.js"></script>

// 2. Write your component
<script type="text/babel">

function Greeting({ name }) {
    const [count, setCount] = React.useState(0);
    return (
        <div onClick={() => setCount(count + 1)}>
            Hello {name}! Clicks: {count}
        </div>
    );
}
</script>

// 3. Use it with ssreact.ComponentName
<div id="ssreact.Greeting"></div>
