| When the Object constructor is called with no arguments the following steps are taken: |
| (The argument value was not supplied or its type was Null or Undefined.) |
| i) Create a new native ECMAScript object. |
| ii) The [[Prototype]] property of the newly constructed object is set to the Object prototype object. |
| iii) The [[Class]] property of the newly constructed object is set to "Object". |
| iv) The newly constructed object has no [[Value]] property. |
| v) Return the newly created native object |
