+### Promisify
+
+Creates a promisified version of the given callback-style function. In Node 8+, you
+can use [`util.promisify`](https://nodejs.org/api/util.html#util_util_promisify_original)
+
+```js
+const promisify = func =>
+  (...args) =>
+    new Promise((resolve, reject) =>
+      func(...args, (err, result) =>
+        err
+        ? reject(err)
+        : resolve(result))
+    )
+// const stat = promisify(fs.stat)
+// stat('foo.txt') -> Promise resolves if `foo.txt` exists, otherwise rejects
+```
+
 ### Random integer in range
 
 Use `Math.random()` to generate a random number and map it to the desired range, using `Math.floor()` to make it an integer.

+### Promisify
+
+Use currying to return a function returning a `Promise` that calls the original function. 
+Use the `...rest` operator to pass in all the parameters.
