This exercise is to understand how to use plain babel and configure it.
The objective of this repo is to use plain babel in order to learn how static transpiling and runtime polyfill works.
Feel free to play with es6.js and add some more ES6 syntax. Assuming you already run yarn install, we can now transpile it by running yarn transpile. This command will generate transpiled-es5.js. Now you can run the final ES5 code with yarn start.
Notice that es6.js uses Promise, and since babel transpiling is static, you need to have a polyfill at runtime that provide the Promise API.
