best of string to number conversion, allowing default NaN or 0

Benchmark created by Including Bitwise Operators on

Setup

var abc = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, '0', '1', '2', '3', '4', '5', '6', '7', '8', '9'], result = 0;

Teardown



            if(result % 90 !== 0)
      throw "Test not implemented properly; result = " + result;
