     | **Key Order**            | Keys are unordered (in practice, insertion order is mostly preserved for string keys, but not guaranteed) | Keys are ordered by insertion; iteration follows insertion order |
     | **Size Property**        | No built-in way to get the number of keys; must use `Object.keys(obj).length` | Use the `.size` property for the number of entries        |
     | **Iterability**          | Not directly iterable; must use `Object.keys`, `Object.values`, or `Object.entries` | Directly iterable with `for...of`, `.keys()`, `.values()`, `.entries()` |
-    | **Prototype**            | Has a prototype chain; may have default properties that can collide with custom keys (can be avoided with `Object.create(null)`) | Does not have a prototype, so there are no default keys   |
+    | **Prototype**            | Has a prototype chain; may have default properties that can collide with custom keys (can be avoided with `Object.create(null)`) | Map does not traverse the prototype chain for key lookup   |
     | **Performance**          | May be less efficient for frequent additions/removals | Optimized for frequent additions and deletions            |
     | **Serialization**        | Can be easily serialized to JSON                    | Cannot be directly serialized to JSON                     |
