displaying react output

i used the book learning react. im unable to display anything on the screen.

React! React! React!

sherlock holmes does not display on my browser. could it be that the links to import react, reactDOM or babel are wrong? how do i get those links myself? where do i get that path to the links that i can get any time. what could be the problem.

Can you please share your full source code? That will help me figure out what may be going on :slight_smile:
