WeekYear

WeekYear adiciona a API .weekYear() para obter o ano da semana (WeekYear) com suporte à localização.

var weekYear = require('dayjs/plugin/weekYear'); // Depende do plugin weekOfYear
// import weekYear from 'dayjs/plugin/weekYear' // ES 2015

var weekOfYear = require('dayjs/plugin/weekOfYear');
// import weekOfYear from 'dayjs/plugin/weekOfYear' // ES 2015

dayjs.extend(weekOfYear);
dayjs.extend(weekYear);

dayjs().weekYear();
