Checks if the given `year` is a leap year.
|
|
|
|
- Use the `Date` constructor, setting the date to February 29th of the given `year`.
|
|
- Use `Date.prototype.getMonth()` to check if the month is equal to `1`.
|
|
|
|
```js
|
|
const isLeapYear = year => new Date(year, 1, 29).getMonth() === 1;
|
|
```
|
|
|
|
```js
|
|
isLeapYear(2019); // false
|
|
isLeapYear(2020); // true
|
|
```
