用moment库

function calcYearAndDateDiff(startDate, endDate) {

const startDateClone = startDate.clone()

const diffYear = endDate.diff(startDateClone, 'year')

const diffDay = endDate.diff(startDateClone.add(diffYear,'years'), 'day')

return [diffYear, diffDay]

}

const startDate= moment('2000-01-01')

const today = moment()

const tomorrow = moment().add(1,'days')

const diff1 = calcYearAndDateDiff(startDate, today)

const diff2 = calcYearAndDateDiff(startDate, tomorrow)
