if (err) return cb(err); be gone!


bash npm install iferr


JavaScript example

```js var iferr = require(‘iferr’);

function get_friends_count(id, cb) { User.load_user(id, iferr(cb, function(user) { user.load_friends(iferr(cb, function(friends) { cb(null, friends.length); })); })); } ```

CoffeeScript example

```coffee iferr = require ‘iferr’

get_friends_count = (id, cb) -> User.load_user id, iferr cb, (user) -> user.load_friends iferr cb, (friends) -> cb null, friends.length ```
