+### Chain asynchronous functions
+
+Loop through an array of functions containing asynchronous events, calling `next` when each asynchronous event has completed.
+
+```js
+const chainAsync = fns => { let curr = 0; const next = () => fns[curr++](next); next(); }
+/* 
+chainAsync([
+  next => { console.log('0 seconds'); setTimeout(next, 1000); },
+  next => { console.log('1 second');  setTimeout(next, 1000); },
+  next => { console.log('2 seconds');}
+])
+*/
