Revision 3 of this benchmark created by Big Numbers on July 23, 2012

Setup

var strs = [];
    for (var i = 0; i < 1000; ++i) {
      strs[i] = '' + (1000000+Math.random() * 1000000000);
    }
    
    window.strs = strs;

Test runner

var nums = [];
for (var i = 0; i < strs.length; ++i)
  nums[i] = Number(strs[i]);
 

var nums = [];
for (var i = 0; i < strs.length; ++i)
  nums[i] = (+strs[i]);
