Package Exports

tinybench
tinybench/benchmark.js
tinybench/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (tinybench) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Development source

Installation

In a browser:

<script src="benchmark.js"></script>

In an AMD loader:

require({
  'paths': {
    'benchmark': 'path/to/benchmark'
  }
},
['benchmark'], function(Benchmark) {/*…*/});

Using npm:

$ npm i --save benchmark

In Node.js:

var Benchmark = require('benchmark');

Optionally, use the microtime module by Wade Simmons:

npm i --save microtime

Usage example:

var suite = new Benchmark.Suite;

// add tests
suite.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
