For my specific situation I only care about the equality of the object as far as keys and primitive values go. The solution that worked for me was converting the object to its JSON representation and using that as the hash. There are limitations such as order of key definition potentially being inconsistent; but like I said it worked for me because these objects were all being generated in one place.

var hashtable = {};

var myObject = {a:0,b:1,c:2};

var hash = JSON.stringify(myObject);
// '{"a":0,"b":1,"c":2}'

hashtable[hash] = myObject;
// {
//   '{"a":0,"b":1,"c":2}': myObject
// }
