请问如下代码应该怎么优化

Question

// select选项过滤,不可重复选择
    filterOptions() {
      const { formData } = this.baseForm;
      // 获取已选项
      const selectOptions = formData.map(item => item.targetName);
      // 根据全部选项与已选选项筛选出差值,计算出每一行候选值
      return formData.map(() => this.indexDetail.filter(v => !selectOptions.includes(v.label)));
    }

试试这样写？不过你的代码简洁性也够了，

filterOptions() {
  const selectOptions = new Set(this.baseForm.formData.map(item => item.targetName));
  return this.baseForm.formData.map(() => this.indexDetail.filter(v => !selectOptions.has(v.label)));
}
