Gets the name of the weekday from a `Date` object.
|
|
|
|
- Use `Date.prototype.toLocaleDateString()` with the `{ weekday: 'long' }` option to retrieve the weekday.
|
|
- Use the optional second parameter to get a language-specific name or omit it to use the default locale.
|
|
|
|
```js
|
|
const dayName = (date, locale) =>
|
|
date.toLocaleDateString(locale, { weekday: 'long' });
|
|
```
|
|
|
|
```js
|
|
dayName(new Date()); // 'Saturday'
|
|
dayName(new Date('09/23/2020'), 'de-DE'); // 'Samstag'
|
|
```
