compare two objects without recursion

compare.js

(function() {

  var obj1 = {
    foo: 'qwerty',
    bar: 'asdfgh',
  };

  var obj2 = {
    foo: '123456',
    bar: '098765',
  };

  var compare = function(a, b) {
    return window.btoa(JSON.stringify(a)) === window.btoa(JSON.stringify(b));
  };

}());

Bad idea, doesn't work with same props in diff order. Rectify unidea this.
