Trying to write my first react-app using node:

my command line results in Windows 10 cmd.exe:

:\Users\ENDER\Desktop>cd react-app

C:\Users\ENDER\Desktop\react-app>npm start
npm ERR! path C:\Users\ENDER\Desktop\react-app/package.json
npm ERR! JSON.parse Unexpected token
npm ERR! JSON.parse  in JSON at position 372 while parsing '{
npm ERR! JSON.parse   "name": "react-app",
npm ERR! JSON.parse   "version": "1'
npm ERR! JSON.parse Failed to parse JSON data.
npm ERR! JSON.parse Note: package.json must be actual JSON, not just JavaScript.

npm ERR! A complete log of this run can be found in:

I will be needing on-going help until I can get this demo running.  I can provide LOGS, directory listings, file contents .. whatever you need.
