Thank you, Eric! I'm glad you found it helpful! :)

Not passing props to the constructor would work just fine, since we aren't using them anywhere inside the constructor function.

Also, when you do super(props) it makes props available on the component instance, inside the constructor. In other words, if you want to use this.props inside the constructor, then use super(props).

React sets .props on the instance from the outside immediately after calling the constructor; making this.props available outside the constructor.

Thank you for the reply! It clarifies a lot.

Nonetheless, if I'm not mistaken, we are using it inside the constructor:

this.state = {
     todos: this.props.dataInterface.getAllTodos(),

By not passing the props, I get "dataInterface undefined".

I was only able to spot it by comparing the code with your repo, which has the super(props) mentioned above.

Maybe we are using different React (or other dependencies) releases?

Once again, thanks for the tutorial
