Answer 1

選項 1： json pipe

<ng-container *ngFor="let item of state">
  {{ item | json }}
</ng-container>

選項 2：鍵值keyvalue

<ng-container *ngFor="let item of state">
  <ng-container *ngFor="let property of item | keyvalue">
    {{ property.key }}: {{ property.value }}
  </ng-container>
</ng-container>

選項 3：直接訪問屬性

<ng-container *ngFor="let item of state">
  {{ item?.name }}
  {{ item?.active }}
  {{ item?.cured }}
  {{ item?.death }}
  ...
</ng-container>
