## 为兄弟元素提供唯一的键属性
|
|
|
|
## 暗示
|
|
|
|
它与之前的[挑战](https://learn.freecodecamp.org/front-end-libraries/react/use-array-map-to-dynamically-render-elements)几乎相同。只需要添加`key`属性。
|
|
|
|
## 解
|
|
|
|
只需将`key`属性添加到`<li>`标记即可使其唯一
|
|
|
|
```jsx
|
|
const renderFrameworks = frontEndFrameworks.map((item) =>
|
|
<li key={item+1}>{item}</li>
|
|
);
|
|
|
|
``` |
