A test of function wrappers compared to the long hand.

Preparation code

 
<script>
  Benchmark.prototype.setup = function() {
    Object.applyEach = function(target, callback) {
        var key = null;
        
        for(key in target) {
            if(target.hasOwnProperty(key)) {
                callback.apply(target, [callback]);
            }
        }
    };
    
    Object.callEach = function(target, callback) {
        var key = null;
        
        for(key in target) {
            if(target.hasOwnProperty(key)) {
                callback.call(target, callback);
            }
        }
    };
    
    var testObject = {},
        copyTo = null;
    
    for(var i = 0; i < 100; i += 1) {
        testObject[i] = i * new Date().getTime();
    }
  };
</script>
