Very nice article, I was looking for react js tutorial around the net and I want to do it in the normal way, without installing npm and all that stuff. So, it’s good one. I’ve two questions:

  1. I’ve taken development Js files from CDN for react, react-dom and babel, they were not working on localhost, but when I just copied above paths and used them, it started working. Where is the difference? Are production and development scripts different in case of React ?
  2. and the script “src” you have taken, can I use that? Is it free to use?
