How to Define a HTML Class in JSX in React

When writing JSX you cant add classes like you would in HTML so this code would not work:

JSX

<div class="my-class"></div>

Instead we have to use className.

JSX uses camel case for a lot of its attributes, like onClick for onclick and onChange for onchange.

HTML

<div id="root"></div>

<script type="text/babel">
const JSX = (
  <div className="myDiv">
    <h1>Add a class to this div</h1>
  </div>
);
ReactDOM.render(JSX, document.getElementById('root'))
</script>
