Checks if the given date is a weekday.
|
|
|
|
- Use `Date.prototype.getDay()` to check weekday by using a modulo operator (`%`).
|
|
- Omit the argument, `d`, to use the current date as default.
|
|
|
|
```js
|
|
const isWeekday = (d = new Date()) => d.getDay() % 6 !== 0;
|
|
```
|
|
|
|
```js
|
|
isWeekday(); // true (if current date is 2019-07-19)
|
|
```
