Explanation

task.service.ts

  • Lines 11–13: The getTasks method returns an Observable that emits an array of Task objects. The of operator from RxJS is used to create an Observable that emits a single value, in this case, the current array of tasks (this.tasks).

  • Lines 15–17: The addTask method takes a Task object as a parameter and adds it to the tasks array. This method is used to simulate adding a new task to the collection.

  • Lines 19–21: The deleteTask method takes a Task object as a parameter and removes it from the tasks array. It uses the filter method to create a new array that includes all tasks, except the one that matches the provided task.
