-A drop-in replacement<sup>[*](https://github.com/bestiejs/lodash/wiki/Drop-in-Disclaimer)</sup> for Underscore.js, from the devs behind [jsPerf.com](http://jsperf.com), delivering [performance](http://lodash.com/benchmarks), [bug fixes](https://github.com/bestiejs/lodash#resolved-underscorejs-issues), and [additional features](http://lodash.com/#features).
+A utility library, usable as a drop-in replacement for Underscore, delivering [performance](http://lodash.com/benchmarks), [bug fixes](https://github.com/bestiejs/lodash#resolved-underscorejs-issues), and [additional features](http://lodash.com/#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.
