+### Async/Await are even cleaner than Promises
+Promises are a very clean alternative to callbacks, but ES7 brings async and await
+which offer an even cleaner solution. All you need is a function that is prefixed
+in an `async` keyword, and then you can write your logic imperatively without
+a `then` chain of functions. Use this if you can take advantage of ES7 features
+today!
+
+**Bad:**
+```javascript
+require('request-promise').get('https://en.wikipedia.org/wiki/Robert_Cecil_Martin')
+ .then(function(response) {
+ return require('fs-promise').writeFile('article.html', response);
+ })
+ .then(function() {
+ console.log('File written');
+ })
+ .catch(function(err) {
+ console.log(err);
+ })
+
+```
+
+**Good**:
+```javascript
+async function getCleanCodeArticle() {
+ try {
+ var request = await require('request-promise')
+ var response = await request.get('https://en.wikipedia.org/wiki/Robert_Cecil_Martin');
+ var fileHandle = await require('fs-promise');
+
+ await fileHandle.writeFile('article.html', response);
+ console.log('File written');
+ } catch(err) {
+ console.log(err);
+ }
+ }
+```
