在前端写逻辑会不会被打死。。。

根据数据中的月份对数据进行排序，月份为String类型。如“1月，2月，3月，11月，12月”

 // 根据月份排序
  monthSort(planList: any[]): any[] {
    if (planList.length == 0) {
      return [];
    }
    let plans;
    let planOne;
    let planTwo;
    let planTwoTemp;
    let planThree;
    let planThreeTemp;
    // 有当前月份
    const isInArray = (arr, value) => {
      for (let i = 0; i < arr.length; i++) {
        if (value === arr[i]) {
          return true;
        }
      }
      return false;
    }
    // 比当前月份大
    const isGreaterArray = (item, value) => {
      const monthNumber = Number(value.slice(0, value.length - 1));
      const imonths = item.months.split(",");
      for (let i = 0; i < imonths.length; i++) {
        let monthTemp = Number(imonths[i].slice(0, imonths[i].length - 1));
        if (monthNumber < monthTemp) {
          return true;
        }
      }
      return false;
    }
    const presentMonth = new Date().getMonth() + 1 + "月";
    // 过滤当前月
    const filterIsInArray = (item, month) => {
      const imonths = item.months.split(",");
      return isInArray(imonths, month);
    }
    // 过滤出一个数组中与其他数组的差值
    const repetition = (item, arr) => {
      const arrids = [];
      for (let i = 0; i < arr.length; i++) {
        arrids.push(arr[i].id);
      }
      let i = arrids.length;
      while (i--) {
        if (arrids[i] === item.id) {
          return false;
        }
      }
      return true;
    }
    // 过滤出当前月
    planOne = [...planList.filter(item => filterIsInArray(item, presentMonth))];
    planTwoTemp = [...planList.filter(item => repetition(item, planOne))];
    planTwo = [...planTwoTemp.filter(item => isGreaterArray(item, presentMonth))];
    planThreeTemp = planOne.concat(planTwo);
    planThree = [...planList.filter(item => repetition(item, planThreeTemp))];
    plans = planThreeTemp.concat(planThree);
    return plans;
  }
