The objFreeze() method freezes an object. A frozen object can no longer be changed; freezing an object
prevents new properties from being added to it, existing properties from being removed, prevents changing the
enumerability, configurability, or writability of existing properties, and prevents the values of existing
properties from being changed. In addition, freezing an object also prevents its prototype from being changed.
objFreeze() returns the same object that was passed in.
Nothing can be added to or removed from the properties set of a frozen object. Any attempt to do so will fail,
either silently or by throwing a TypeError exception (most commonly, but not exclusively, when in strict mode).
For data properties of a frozen object, values cannot be changed, the writable and configurable attributes are
set to false. Accessor properties (getters and setters) work the same (and still give the illusion that you are
changing the value). Note that values that are objects can still be modified, unless they are also frozen. As
an object, an array can be frozen; after doing so, its elements cannot be altered and no elements can be added
to or removed from the array.
objFreeze() returns the same object that was passed into the function. It does not create a frozen copy.
