💻 Code

export interface RecallStrategyForm {
  target1: string;
  target2?: string;
  getType: string;
  inputId: string;
  templateTag: string;
  limit: {
    quota: string;
    sign: string;
    num: number;
  };
  recallWeight: number;
  recallOrder: string;
  recallBasis: number;
  recallMax: number;
  dateRange: number[];
  isCompletion: boolean;
  completionNum: number;
}

export interface RecallStrategyTable {
  id: string;
  target: string;
  rule: string;
  basis: string;
  weight: string;
  order: string;
  maxNum: number;
  isCompletion: string;
  dateRange: string;
}

export interface RecallStrategyDetail {
  id: string;
  no: number;
  itemId: string;
  itemName: string;
  totalMake: number;
  '7Make': number;
  '3Make': number;
  activeDay: number;
  cover: string;
  templateType: string;
}

type formKey = keyof RecallStrategyForm
type tableKey = keyof RecallStrategyTable
type detailKey = keyof RecallStrategyDetail

🙁 Actual behavior

We can see that the result order of one is different from the order of the other two, the other two are arranged in the order of declaration, but the middle one is not;

🙂 Expected behavior

I hope the order of return is in accordance with the order of declaration or a fixed way;
