WeekYear

WeekYear 增加了 .weekYear() API 来获取基于当前语言的按周计算的年份。

var weekYear = require("dayjs/plugin/weekYear"); // dependent on weekOfYear plugin
// 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();
