How to use the react-day-picker.DateUtils.isDayInRange function in react-day-picker

    ranges.some(v => DateUtils.isDayInRange(day, v));

selected: day =>
        DateUtils.isDayInRange(day, this.state) ||
        this.state.ranges.some(v => DateUtils.isDayInRange(day, v)),
    };

    const selectedDays = day => DateUtils.isDayInRange(day, this.state) ||
    ranges.some(v => DateUtils.isDayInRange(day, v));

        this.state.ranges.some(v => DateUtils.isDayInRange(day, v)),
    };

        this.state.ranges.some(v => DateUtils.isDayInRange(day, v)),
    };

        ranges.some(v => DateUtils.isDayInRange(day, v));
      const dateInRanges = _.flatten(ranges.map(range => [range.from, range.to]));

          this.state.ranges.some(v => DateUtils.isDayInRange(day, v)),
      };

selected: day =>
        DateUtils.isDayInRange(day, this.state) ||
        this.state.ranges.some(v => DateUtils.isDayInRange(day, v)),
    };

        DateUtils.isDayInRange(day, dates) ||
        ranges.some(v => DateUtils.isDayInRange(day, v));
      const dateInRanges = _.flatten(ranges.map(range => [range.from, range.to]));
