IsLeapYear

IsLeapYear adds .isLeapYear API to returns a boolean indicating whether the Dayjs's year is a leap year or not.

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

dayjs.extend(isLeapYear);

dayjs("2000-01-01").isLeapYear(); // true
