files.component.html hasOwnProperty error in Visual Studio [SOLVED]

[vurda69]

To avoid the hasOwnProperty error in Visual Studio, I made the following changes in my local copy. Hope it's a useful contribution :)

files.component.html

<span class="files__info-value"> {{ content.size }}<span class="files__info-unit">mb</span> </span>
        <span class="files__info-value" *ngIf="verify_list(content, 'filamentWeight')">
          {{ get_list_property(content, "filamentWeight") }}<span class="files__info-unit">g</span>
        </span>
        <span class="files__info-value" *ngIf="verify_list(content, 'printTime')">
          {{ get_list_property(content, 'printTime') }}<span class="files__info-unit">h</span>
        </span>
      </div>
      <span class="files__name">
        {{ content.name }}
      </span>
    </div>
  </div>
  <div class="scroll__thumb-inactive" *ngIf="folderContent"></div>
</div>

<div class="file" id="fileDetailView">
  <div class="file__wrapper" *ngIf="fileDetail && fileDetail.name !== 'error'">
    <img src="assets/error.svg" class="file__close" (click)="closeDetails()" />
    <span class="file__name">{{ fileDetail.name }}</span>
    <span class="file__directory">{{ fileDetail.path }}</span>
    <span class="file__creation-date" *ngIf="verify_list(fileDetail, 'date')">{{ fileDetail.date }}</span>
    <img [src]="fileDetail.thumbnail" class="file__render" />
    <table class="file__details">
      <tr>
        <td>{{ fileDetail.size }}<span class="file__details-name">mb</span></td>
      <td *ngIf="verify_list(fileDetail, 'printTime')">
          {{ fileDetail.printTime }}<span class="file__details-name">h</span>
        </td>
        <td *ngIf="verify_list(fileDetail, 'filamentWeight')">

files.component.ts

  public verify_list(lista:{}, key:string):boolean {
    if (lista.hasOwnProperty(key)){
      return true
    }
    return false
  }

  public get_list_property(lista:{}, key:string): string{
    return lista[key]
  }
