# --description--
|
||
|
||
JSX 是一种可以编译成 JavaScript 的语法。 有时,为了便于阅读,可能需要在代码中添加注释。 像大多数编程语言一样,JSX 也有自己的方法来实现这一点。
|
||
|
||
要将注释放在 JSX 中,可以使用 `{/* */}` 语法来包裹注释文本。
|
||
|
||
# --instructions--
|
||
|
||
代码编辑器中的 JSX 元素与在上一个挑战中创建的元素类似。 在提供的 `div` 元素里添加注释,不修改现有的 `h1` 或 `p` 元素。
|
||
|
||
# --hints--
|
||
|
||
常量 `JSX` 应该返回一个 `div` 元素。
|
||
|
||
```js
|
||
assert(JSX.type === 'div');
|
||
```
|
||
|
||
`div` 应该包含一个 `h1` 标签作为第一个元素。
|
||
|
||
```js
|
||
assert(JSX.props.children[0].type === 'h1');
|
||
```
|
||
|
||
`div` 应该包含一个 `p` 标签作为第二个元素。
|
||
|
||
```js
|
||
assert(JSX.props.children[1].type === 'p');
|
||
```
|
||
|
||
当前的 `h1` 和 `p` 元素不能被修改。
|
||
|
||
```js
|
||
assert(
|
||
JSX.props.children[0].props.children === 'This is a block of JSX' &&
|
||
JSX.props.children[1].props.children === "Here's a subtitle"
|
||
);
|
||
```
|
||
|
||
`JSX` 应该包含一个注释。
|
||
|
||
```js
|
||
assert(/<div>[\s\S]*{\s*\/\*[\s\S]*\*\/\s*}[\s\S]*<\/div>/.test(code));
|
||
```
|
||
|
||
# --seed--
|
||
|
||
## --after-user-code--
|
||
|
||
```jsx
|
||
ReactDOM.render(JSX, document.getElementById('root'))
|
||
```
|
||
|
||
## --seed-contents--
|
||
|
||
```jsx
|
||
const JSX = (
|
||
<div>
|
||
<h1>This is a block of JSX</h1>
|
||
<p>Here's a subtitle</p>
|
||
</div>
|
||
);
|
||
```
|
||
|
||
# --solutions--
|
||
|
||
```jsx
|
||
const JSX = (
|
||
<div>
|
||
<h1>This is a block of JSX</h1>
|
||
{ /* this is a JSX comment */ }
|
||
<p>Here's a subtitle</p>
|
||
</div>);
|
||
```
