Running ES2015 modules in the browser and with Node.js

Let's try to run the 17-ES2015-ES6-Modules.js file with Node.js by changing the directory and then executing the node command as follows:

    cd path-source-bundle/examples/chapter01
    node 17-ES2015-ES6-Modules
  

We will get an error, SyntaxError: Unexpected token import. This is because at the time of writing this book, Node.js does not support ES2015 native modules. Node.js uses CommonJS module require syntax, and this means we need to transpile our ES2015 so Node can understand it. There are different tools we can use for this task. To keep things simple, we will use Babel CLI.

The complete setup and detailed use of Babel can be found at https://babeljs.io/docs/setup and https://babeljs.io/docs/usage/cli/ ...
