dayjs前10个月;实现（坐牢一年是不是10个月）

import moment from 'dayjs'
initTimeDurations=()=>{
    let beforeMonth = (monthDuration:Number)=>{
      let currentMonth = moment().month();
      let currentYear = moment().year();
      let arr = []
      for(let i = 0;i < monthDuration ; i++ ){
        let handle = moment().subtract(i, 'month')
        let year = handle.year();
        let month = handle.month();
        let template = `${year}年${month+1}月`
        arr.push(template)        
      }
      return arr
    }
    this.timeDurations = [
      '近七天',
      ...beforeMonth(6)
    ]
 }

开源库提供了很大的方便啊；dayjs
