Benchmark created on October 4, 2011

Preparation HTML

<script>
  var hot = (function (undefined) {
        var toString = Object.prototype.toString;
        
        var hot = function () {
                //....
        };
        
        var typeOf = hot.typeOf = function (val) {
                var type = typeof val;  //Ok if not then let's define type using typeof statement
                
                if (type !== "object") return type; //If type not equal to object then ok but else
                
                if (val === null) return "null"; //Maybe val is null ?          
                if (val.length !== undefined) return "array"; //Maybe it's array?
                
                return "object"; //Ok, it's object
        };
        
        return hot;
  })();
