Benchmark.js’ only hard dependency islodash.Includeplatform.js to populateBenchmark.platform.
In a browser:
<scriptsrc="lodash.js"></script><scriptsrc="platform.js"></script><scriptsrc="benchmark.js"></script>
Optionally, enable Chrome’s microsecond timer by using thecommand line switch:
--enable-benchmarkingIn an AMD loader:
require({'paths':{'benchmark':'path/to/benchmark','lodash':'path/to/lodash','platform':'path/to/platform'}},['benchmark'],function(Benchmark){/*…*/});
Using npm:
$ npm i --save benchmark
In Node.js:
varBenchmark=require('benchmark');
Optionally, use themicrotime module by Wade Simmons:
npm install microtime
Usage example:
varsuite=newBenchmark.Suite;// add testssuite.add('RegExp#test',function(){/o/.test('Hello World!');}).add('String#indexOf',function(){'Hello World!'.indexOf('o')>-1;})// add listeners.on('cycle',function(event){console.log(String(event.target));}).on('complete',function(){console.log('Fastest is '+this.filter('fastest').map('name'));})// run async.run({'async':true});// logs:// => RegExp#test x 4,161,532 +-0.99% (59 cycles)// => String#indexOf x 6,139,623 +-1.00% (131 cycles)// => Fastest is String#indexOf
Tested in Chrome 46-47, Firefox 42-43, IE 9-11, MS Edge 13, Safari 8-9, Node.js 0.8.28, 0.10.41, 0.12.9, 4.2.4, & 5.3.0, & PhantomJS 1.9.8.
Benchmark.js is part of the BestieJS“Best in Class” module collection. This means we promote solid browser/environment support, ES5+ precedents, unit testing, & plenty of documentation.
