On line 77 in KanbanBoardContainer.addCard (chapter 5) you have:
newTask.id=responseData.id
this.setState({cards:nextState});
I noticed that you call setState with nextState before the ajax call. And you called setState with nextState after the ajax call. Isn't that mutating the deep state of nextState but returning the same pointer. In other words, why not use the "Immutability Helper update" method?
I thought that the whole reason for using "Immutability Helper update" was because you should't mutate the original object?
