Utilize a variable from one Angular component in another by sharing it between .ts files

My issue involves dynamically adding items to a todo list and wanting to exclude certain items. The challenge lies in the fact that the list itself is located outside of the task component:

Within the task.component.html file, I iterate through the list for display:

<ul class="list-group" *ngFor="let taskElement of taskElements; let i=index" [taskElement]="taskElement">
<div class="d-flex justify-content-center">
    <li class="list-group-item">
        <span>
            {{element.description}}
        </span>
        <button class="btn btn-danger" style="float: right;" type="button">Remove
            Task</button>
    </li>

However, the list itself is defined in the app.component.ts file:

public containsTask = false;
  taskElements: { description: string, isDone: boolean }[] = [];

  onTaskCreated(taskData: { taskDescription: string }) {
    this.taskElements.push({
      description: taskData.taskDescription,
      isDone: false
    });
    this.containsTask = true;
  }

I am looking for a way to utilize the taskElements array declared in app.component.ts within the task.component.ts. Any suggestions would be greatly appreciated!

Thank you!

To streamline data management, consider using a service. By injecting this service into multiple components, you can conveniently access the array it contains.
