 In that case the visitor may choose "__proto__" as the key, and the assignment logic will be ruined (as shown above).

 ### Ordered like an object
 
-Are objects ordered? In other words, if we loop over an object, do we get all properties in the same order that they are added in it? Can we rely on it?
+Are objects ordered? In other words, if we loop over an object, do we get all properties in the same order they were added? Can we rely on this?
 
 The short answer is: "ordered in a special fashion": integer properties are sorted, others appear in creation order. The details follow.

-For comparisons like `obj1 > obj2` or for a comparison against a primitive `obj == 5`, objects are converted to primitives. We'll study how object conversions work very soon, but to say the truth, such comparisons are necessary very rarely and usually are a result of a coding mistake.
