As Fernando said, why not just use an array of objects if you are
about the length?
Also, can the config object contain things that are not objects?
in ES5, you can do Object.keys(config).length as Object.keys returns
an array of the keys of the object.
If it is not homogenous, you can do something like
var p, size = 0;
for(p in config)
if( typeof config[p] == "object")
size++;
size;
Of course, you'll want to double check for arrays as well.
