我在测试应用程序中注意到奇怪的行为，每当我用新数组覆盖存储时，似乎旧状态仍在内存中（只有最近的条应该是蓝色的）

出于测试目的，我每5秒调度10次加载操作。

ngOnInit() {
    setInterval(() => {
      for (let i = 0; i < 10; i++) {
        this.store.dispatch(CharacterActions.getCharacters());
      }
    }, 5000);
  }

我的店就是这个样子

export interface CharacterState {
  characters: Character[];
}

export const initialState: CharacterState = {
  characters: [],
};

export const characterReducer = createReducer(
  initialState,
  on(CharacterActions.getCharactersSuccess, (state, { characters }) => ({
    ...state,
    characters: [...characters],
  }))
);

和性格类

import { Weapon } from "./weapon";

export class Character {
    name: string;
    surname: string;
    private weapons: Weapon[];

    constructor(name: string, surname: string, weapons?: Weapon[]) {
        this.weapons = weapons ?? [];
        this.name = name;
        this.surname = surname;
    }

    public getWeapons(): Weapon[] {
        return this.weapons;
    }

    public addWeapon(weapon: Weapon): void {
        this.weapons.push(weapon);
    }

    public upgradeWeapon(name: string, value: number) {
        this.weapons.find(x => x.name === name.toLowerCase())?.upgrade(value);
    }
}
