What is the best way to merge two approaches for tallying items within each category?

I have an Angular 8 application that includes two methods for displaying the number of items in each category. These items are retrieved from the back-end and are categorized as follows:

  <mat-tab>
          <ng-template mat-tab-label>
            <mat-icon class="goals">grade</mat-icon>
            <span i18n>Goals</span>{{ dossierItemsCountString(itemTypes.Goal) }}
            <a [routerLink]="['../', dossier.id, 'item', 'new', itemTypes.Goal]"
              ><mat-icon class="add_box">add</mat-icon>
            </a>
          </ng-template>
...

In order to show the items per category, there are two functions implemented:


  dossierItemsCountBy(itemType: DossierItemTypeDto) {
    return this.typeSearchMatches[itemType.toString()] || { total: 0, matches: 0 };
  }

  dossierItemsCountString(itemType: DossierItemTypeDto) {
...

I am considering combining these two methods into a single method or creating a custom Pipe. What would be the best approach for this? How can I implement it effectively?

Your insights and suggestions will be greatly appreciated.

Answer №1

I'm unsure about the best way to respond to the query "what is the most effective approach?".

Nevertheless, adjusting dossierItemsCountString() in this manner should produce the desired outcome:

const count = this.typeSearchMatches[itemType.toString()] || { total: 0, matches: 0 };
