# --description--
|
|
|
|
The last challenge was a simple example of JSX, but JSX can represent more complex HTML as well.
|
|
|
|
One important thing to know about nested JSX is that it must return a single element.
|
|
|
|
This one parent element would wrap all of the other levels of nested elements.
|
|
|
|
For instance, several JSX elements written as siblings with no parent wrapper element will not transpile.
|
|
|
|
Here's an example:
|
|
|
|
**Valid JSX:**
|
|
|
|
```jsx
|
|
<div>
|
|
<p>Paragraph One</p>
|
|
<p>Paragraph Two</p>
|
|
<p>Paragraph Three</p>
|
|
</div>
|
|
```
|
|
|
|
**Invalid JSX:**
|
|
|
|
```jsx
|
|
<p>Paragraph One</p>
|
|
<p>Paragraph Two</p>
|
|
<p>Paragraph Three</p>
|
|
```
|
|
|
|
# --instructions--
|
|
|
|
Define a new constant `JSX` that renders a `div` which contains the following elements in order:
|
|
|
|
An `h1`, a `p`, and an unordered list that contains three `li` items. You can include any text you want within each element.
|
|
|
|
**Note:** When rendering multiple elements like this, you can wrap them all in parentheses, but it's not strictly required. Also notice this challenge uses a `div` tag to wrap all the child elements within a single parent element. If you remove the `div`, the JSX will no longer transpile. Keep this in mind, since it will also apply when you return JSX elements in React components.
|
|
|
|
# --hints--
|
|
|
|
The constant `JSX` should return a `div` element.
|
|
|
|
```js
|
|
assert(JSX.type === 'div');
|
|
```
|
|
|
|
The `div` should contain an `h1` tag as the first element.
|
|
|
|
```js
|
|
assert(JSX.props.children[0].type === 'h1');
|
|
```
|
|
|
|
The `div` should contain a `p` tag as the second element.
|
|
|
|
```js
|
|
assert(JSX.props.children[1].type === 'p');
|
|
```
|
|
|
|
The `div` should contain a `ul` tag as the third element.
|
|
|
|
```js
|
|
assert(JSX.props.children[2].type === 'ul');
|
|
```
|
|
|
|
The `ul` should contain three `li` elements.
|
|
|
|
```js
|
|
assert(
|
|
JSX.props.children
|
|
.filter((ele) => ele.type === 'ul')[0]
|
|
.props.children.filter((ele) => ele.type === 'li').length === 3
|
|
);
|
|
```

const JSX = (
|

<div>
|

|
|
<p>Some info</p>
|
|
<ul>
|
|
<li>An item</li>
|
|
<li>Another item</li>
|
|
<li>A third item</li>

</ul>
|

</div>);
