js实现获取日期区间内所有日期

// value为日期数组，例 ["2022-12-13","2022-12-20"]
getBeforeTime (value) {
    
    
      let arr = []
      let str_b = value[0].split('-')
      let str_e = value[1].split('-')
      let date_b = new Date()
      date_b.setUTCFullYear(str_b[0], str_b[1] - 1, str_b[2])
      let date_e = new Date()
      date_e.setUTCFullYear(str_e[0], str_e[1] - 1, str_e[2])
      let unixDb = date_b.getTime() - 24 * 60 * 60 * 1000
      let unixDe = date_e.getTime() - 24 * 60 * 60 * 1000
      for (let j = unixDb; j <= unixDe;) {
    
    
        j = j + 24 * 60 * 60 * 1000
        arr.push(this.timestampToTime(new Date(parseInt(j))))
      }
      console.log(arr);
    },
    timestampToTime (date) {
    
    
      var Y = date.getFullYear() + '-';
      var M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1) + '-';
      var D = date.getDate();
      return Y + M + D;
    },
