I’ve never been so infuriated by an example before. “Don’t mind the details” just try to understand what the code is trying to do? Why not explain the details before putting it together and overwhelming the student? It’s asinine. Try to understand why multiple constants are being defined at the same time to an empty object or array? We have used prevProps, but now there are prevState and prev? Thankfully I’ve seen the spread syntax before but if I didn’t that’s another brand new concept. Shame on whoever designed this course. I am not going to be continuing with my subscription. This is horrible.


Can anyone tell me why we need to set a unique ID for every onChange event in the text input field.
Why not create a unique Id for the newTodo onSubmit and store it in AllTasks array.
