Hey Ray and Bill, sorry for the delay — Medium didn’t notify me of your responses. That will be because you haven’t passed any data in to your ToDo List, so it cannot render anything. I’m not sure why your <List/> component is rendering without anything if you have been using the same component from the tutorial. To be sure, check out the List component here: https://bit.dev/sunil-sandhu/react-components/list

You will notice that it is importing a font.css file which gives it the font, and also has a regular JavaScript object that is being passed to the List component as a prop. It is being passed as items which should remedy the TypeError you had been receiving. Hope that helps!
