I was just wondering if this is production code or just example of node and I should fill in blanks by writing a function and missing parts? "(res)=>" and ${})??? Is this literal ?
http.get('http://www.google.com/index.html', (res) => {
console.log(Got response: ${res.statusCode});
// consume response body
res.resume();
}).on('error', (e) => {
console.log(Got error: ${e.message});
});

That would be the same as writing "function (res)" in older versions of JS. And the ${} is how you do interpolation. This allows you to dynamically pass in values. Hope that helps! If you want to up your knowledge more on ES2015 here is a great resource: https://babeljs.io/docs/learn-es2015/
