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
