simple benchmarking snippet for v8 & node

test.js

function test() {
    for (var i = 0, array = []; i < 1000; i++) array.push(i, i);
}

var start = Date.now(), ops = 0;
do { test(); ops++; } while (Date.now() - start < 1000);
(typeof console !== 'undefined' ? console.log : print)(ops + ' ops/s');
