Dave, you're a priceless teacher. In my opinion, it's easy to understand the topic you're explaining because you talk about the tiny details as well, while many others think that beginners should understand the obvious things, which is often not the case. Thank you!

Thanks for breaking this down. 1/2 way through I was hoping you would do that. On the <LineItem component you added in key={item.id} attribute which I understand why, does this mean we don't need it on the <li> now within the LineItem component itself. I removed it didn't appear to error. Great tutorial, thanks.

I remember feeling like React is so messy and confusing at first, but that was because my code was unorganized and written really badly. I now find it so beautiful and quick to create things with, haha. Creating and managing components is addictive!

[sheilakerber]

Your explanations are amazing. Really grateful! <3

[toonice]

Great video! I'd love to know why you chose to use an icon with roles and aria labels rather than wrapping the icon in a <button> element? Wouldn't that solve all the accessibility issues and also keep the HTML semantic? Thanks again

[vivekanand]

Your explanation is great I really like the way you explain in great details.
