Installation

Benchmark.js’ only hard dependency is lodash. Include platform.js to populate Benchmark.platform.

In a browser:

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

Using npm:

$ {sudo -H} npm i -g npm
$ npm i --save benchmark

In Node.js:

var Benchmark = require('benchmark');

Optionally, use the microtime module for Node.js by Wade Simmons:

$ npm i --save microtime
