+A drop-in replacement for Underscore.js, from the devs behind [jsPerf.com](http://jsperf.com), that delivers [performance improvements](http://lodash.com/benchmarks), [bug fixes](https://github.com/bestiejs/lodash#closed-underscorejs-issues), and [additional features](https://github.com/bestiejs/lodash#features).

 Lo-Dash’s performance is gained by avoiding slower native methods, instead opting for simplified non-ES5 compliant methods optimized for common usage, and by leveraging function compilation to reduce the number of overall function calls.

 ## Custom builds

 Custom builds make it easy to create lightweight versions of Lo-Dash containing only the methods you need.
 We handle all the method dependency and alias mapping for you.

-Mobile builds, with IE bug fixes and method compilation removed, may be created by using the `mobile` argument.
+ * Backbone builds, containing all methods required by Backbone, may be created using the `backbone` modifier argument.
+~~~ bash
+node build backbone
