# --description--
|

|
|
|

|
|
Now that you're getting comfortable writing JSX, you may be wondering how it differs from HTML.
|
||
|
|
|
||
|
|
So far, it may seem that HTML and JSX are exactly the same.
|
||
|
|
|
||
|
|
One key difference in JSX is that you can no longer use the word `class` to define HTML classes. This is because `class` is a reserved word in JavaScript. Instead, JSX uses `className`.
|
||
|
|
|
||
|
|
In fact, the naming convention for all HTML attributes and event references in JSX become camelCase. For example, a click event in JSX is `onClick`, instead of `onclick`. Likewise, `onchange` becomes `onChange`. While this is a subtle difference, it is an important one to keep in mind moving forward.
|
||

|
|

|
|
# --instructions--
|
||
|
|
|
||
|
|
Apply a class of `myDiv` to the `div` provided in the JSX code.
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
The constant `JSX` should return a `div` element.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert.strictEqual(JSX.type, 'div');
|
||
|
|
```
|
||
|
|
|
||
|
|
The `div` should have a class of `myDiv`.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert.strictEqual(JSX.props.className, 'myDiv');
|
||
|
|
```
|
||

const JSX = (
|
||

<div>

<h1>Add a class to this div</h1>
|

</div>
|

);

```jsx
|

const JSX = (
|
||
|
|
<div className = 'myDiv'>
|
||
|
|
<h1>Add a class to this div</h1>
|

|

</div>);
