So I’ll start with a general question, do you offer the complete code to your chapter solutions? It would sometimes be easier to see where I went wrong if I could compare my code to yours. That being said, I’m having an issue here in Chapter 3 where my Hello, World is not rendering. Any thoughts: ``` Hello, World!

You can find the source code for the examples here: [kirupa/reactjs at master · kirupa/kirupa · GitHub](https://github.com/kirupa/kirupa/tree/master/reactjs) For this problem (and many problems like this in general), take a look at your browser’s DevTools Console: ![image](https://canada1.discourse-cdn.com/flex011/uploads/kirupa/original/2X/0/0c98ce7caa33f7ae62f185d0bc5eac1c5db017b4.jpeg) Notice the **ReactDom** error. The reason for this error is that the **DOM** part of **ReactDOM** is capitalized. Once you make that adjustment, your example should work just fine 🙂 Cheers, Kirupa ---

Thanks, just the type of tips I needed! If the book goes to a next edition, I’d suggest putting the tip about using the DevTools console. I eyeballed between the text and my code but did not see the difference, the console brings it out in Hi Def color! Regards, Matt ---

I am just starting to learn about codes and I think these codes are great. I am not that great about it yet but I think it’s a small progress that I understand some of them
