모멘트를 통한시간 값 비교 시 format 적용방법

moment_diff.ts

import moment from 'moment'
import 'moment-duration-format'

let currentMoment = moment()
let currentMinuteNum = Number(currentMoment.format('mm'))

let nextMin = 1

let _nextContractTime = moment(currentMoment)
    .add(nextMin, 'minute')
    .set('second', 0)

let _remainTimeSecond = _nextContractTime.diff(
    currentMoment,
    'milisecond'
)
let remainTime = moment.duration(_remainTimeSecond).format('mm:ss')
