A [robust](http://calendar.perfplanet.com/2010/bulletproof-javascript-benchmarks/ "Bulletproof JavaScript benchmarks") benchmarking library that works on nearly all JavaScript platforms<sup><a name="fnref1" href="#fn1">1</a></sup>, supports high-resolution timers, and returns statistically significant results. As seen on [jsPerf](http://jsperf.com/).
