Code samples from the talk "Next Generation JavaScript with ES 2015" at ONE LOGIC.
Run npm install to install babel and the 'es2015' preset. Then you can call npm run b <file> to transpile individual file to ES5 or npm run bn <file> to execute the file. Many of the files contain ES5 as well as ES2015 code. Make sure to comment out the ES5 code to prevent errors because of duplicate definitions.
The code samples are largely inspired by Axel Rauschmayer and Babel
