# --description--
|
|
|
|
在 `keywords` 字段中可以使用相關的關鍵字描述項目。 下面是一個示例：
|
|
|
|
```json
|
|
"keywords": [ "descriptive", "related", "words" ],
|
|
```
|
|
|
|
正如你所見的，這個字段的結構是一個由雙引號字符串組成的數組。
|
|
|
|
# --instructions--
|
|
|
|
在 package.json 文件中，給 `keywords` 字段添加一個由適當的字符串組成的數組。
|
|
|
|
“freecodecamp”應該是關鍵詞之一。
|
|
|
|
# --hints--
|
|
|
|
package.json 應該有一個有效的“keywords”鍵
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/package.json').then(
|
|
(data) => {
|
|
var packJson = JSON.parse(data);
|
|
assert(packJson.keywords, '"keywords" is missing');
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
“keywords”字段應該是一個數組
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/package.json').then(
|
|
(data) => {
|
|
var packJson = JSON.parse(data);
|
|
assert.isArray(packJson.keywords, '"keywords" is not an array');
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
“keywords”中應該包含關鍵詞“freecodecamp”
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/package.json').then(
|
|
(data) => {
|
|
var packJson = JSON.parse(data);
|
|
assert.include(
|
|
packJson.keywords,
|
|
'freecodecamp',
|
|
'"keywords" does not include "freecodecamp"'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
