Open the index.html in your browser, via a local server, to use the compiled, native JavaScript of the survey. You will need to compile the JSX to JS first, however, by using React Tools. If you are using NPM, you can install like so:
// Install support packages
npm install
// Build the /javascript/compiled/app.js file
npm run build
// Note "npm run build" is a package.json script, which call jsx binary like so:
jsx --extension jsx javascript/src javascript/compiled"
React prefers to run its code through a proper HTTP server rather than directly through the file system. I use SublimeServer, which I've installed as a package for Sublime Text.
