在功能上修正无param-重新分配Eslint问题

Question

在下面的代码中，我得到了ESlint error Assignment to property of function parameter 'recurrence'，它位于我// eslint-disable-next-line no-param-reassign禁用行的许多地方。我不想使用禁用。如何解决这个问题，而不使用禁用作为合法的方式？有人能帮我吗？谢谢

   onUpdateRecurrence = (recurrence) => {
    const todayDay = moment().format('D');
    const currentMonth = moment().format('M');
    if (recurrence.frequency === 'MONTHLY') {
      if (recurrence.days) {
        // eslint-disable-next-line no-param-reassign
        delete recurrence.days;
      }
      if (recurrence.day_of_month) {
        // eslint-disable-next-line no-param-reassign
        recurrence.day_of_month = recurrence.day_of_month;
      } else {
        // eslint-disable-next-line no-param-reassign
        recurrence.day_of_month = `${todayDay}${this.getDaySuffix(todayDay)}`;
      }
      if (recurrence.month) {
        // eslint-disable-next-line no-param-reassign
        recurrence.month = recurrence.month;
      } else {
        // eslint-disable-next-line no-param-reassign
        recurrence.month = currentMonth;
      }
    }
    if (recurrence.frequency === 'WEEKLY') {
      if (recurrence.day_of_month) {
        // eslint-disable-next-line no-param-reassign
        delete recurrence.day_of_month;
      }
      if (recurrence.month) {
        // eslint-disable-next-line no-param-reassign
        delete recurrence.month;
      }
    }
    if (recurrence.frequency === 'DAILY') {
      if (recurrence.day_of_month) {
        // eslint-disable-next-line no-param-reassign
        delete recurrence.day_of_month;
      }
      if (recurrence.month) {
        // eslint-disable-next-line no-param-reassign
        delete recurrence.month;
      }
      if (recurrence.days) {
        // eslint-disable-next-line no-param-reassign
        delete recurrence.days;
      }
    }
    return recurrence;
  };

您可以将递归赋值给函数中的const变量，并在函数旁边使用它。

 onUpdateRecurrence = (recurrence) => {
    const recurrenceValue = {...recurrence};

   //Your Code
 }
