Check if a date is between two other dates
|
|
|
|
- Use the greater than operator (`>`) to check if the `date` comes after the `dateStart`.
|
|
- Use the less than operator (`<`) to check if the `date` comes before the `dateEnd`.
|
|
- Use the logical and operator (`&&`) to check if the `date` is between the `dateStart` and the `dateEnd`.
|
|
|
|
```js
|
|
const isBetweenDates = (dateStart, dateEnd, date) => date > dateStart && date < dateEnd;
|
|
```
|
|
|
|
```js
|
|
isBetweenDates(new Date(2010, 11, 20), new Date(2010, 11, 30), new Date(2010, 11, 19)); // false
|
|
isBetweenDates(new Date(2010, 11, 20), new Date(2010, 11, 30), new Date(2010, 11, 25)); // true
|
|
isBetweenDates(new Date(2010, 11, 20), new Date(2010, 11, 30), new Date(2010, 11, 31)); // false
