SetDefaultGlobalBindings ( realmRec )
1. Let global be realmRec.[[GlobalObject]].
2. For each property of the Global Object specified in clause 19, do
a. Let name be the String value of the property name.
b. Let desc be the fully populated data Property Descriptor for the property, containing the specified attributes for the property. For properties listed in 19.2, 19.3, or 19.4 the value of the [[Value]] attribute is the corresponding intrinsic object from realmRec.
c. Perform ? DefinePropertyOrThrow(global, name, desc).
3. Return global.
