# --hints--
|
|
|
|
`getDateFormats`是一个函数。
|
|
|
|
```js
|
|
assert(typeof getDateFormats === 'function');
|
|
```
|
|
|
|
应该返回一个对象。
|
|
|
|
```js
|
|
assert(typeof getDateFormats() === 'object');
|
|
```
|
|
|
|
应该返回一个包含2个元素的数组。
|
|
|
|
```js
|
|
assert(getDateFormats().length === 2);
|
|
```
|
|
|
|
应以正确的格式返回正确的日期
|
|
|
|
```js
|
|
assert.deepEqual(getDateFormats(), dates, equalsMessage);
|
|
```
