# --hints--
|
|
|
|
`getDateFormats` should be a function.
|
|
|
|
```js
|
|
assert(typeof getDateFormats === 'function');
|
|
```
|
|
|
|
`getDateFormats` should return an object.
|
|
|
|
```js
|
|
assert(typeof getDateFormats() === 'object');
|
|
```
|
|
|
|
`getDateFormats` should return an array with 2 elements.
|
|
|
|
```js
|
|
assert(getDateFormats().length === 2);
|
|
```
|
|
|
|
`getDateFormats` should return the correct date in the right format
|
|
|
|
```js
|
|
assert.deepEqual(getDateFormats(), dates, equalsMessage);
|
|
```
