Checks if a date is before another date.
|
|
|
|
- Use the less than operator (`<`) to check if the first date comes before the second one.
|
|
|
|
```js
|
|
const isBeforeDate = (dateA, dateB) => dateA < dateB;
|
|
```
|
|
|
|
```js
|
|
isBeforeDate(new Date(2010, 10, 20), new Date(2010, 10, 21)); // true
|
|
```
