This code deletes the object on the server.

private deleteTask(taskId: number) { this.serv.deleteTask(taskId).subscribe(data => { if (data.status) { let index = this.tasks.indexOf(taskId); this.tasks.splice(index, 1); } }, error => console.log(error) ); }

And I want to delete a line (element In DOM) by index in View. But the studio swears at indexOf(taskId) and writes:

Error TS2345 (TS) Argument of type 'number' is not assignable to parameter of type 'Task'

  let index = this.tasks.indexOf((taskId: number)); но не помогло.

How to delete an item by index?

    Perhaps it is worth replacing both lines inside if by this.tasks = this.tasks.filter(task => task.id !== taskId) - diraria

In this form it works

  if (data.status) { this.tasks = this.tasks.filter(task => task.id !== taskId); }
