Testing ES6 syntax files independently for React projects (incl .Ravenous)


I was working on the Ravenous project earlier and was able to follow all the steps and get everything to work. However, I couldn’t figure out a way to test out individual files. For example, for the Yelp.js file, I added a console.log statement to print the output of the API request, and to run the file independently, in the console on VS Code i tried to do “node Yelp.js”, and go the error below. I believe this has to do with the fact that the file is in ES6 syntax and when I do "node " it doesn’t understand that syntax (where as when I do “npm start” it understands it). How can I test individual files in VS Code? Thanks!
