Property names are returned in ascending chronological order of creation

EnumerateObjectProperties ( O )
EnumerateObjectProperties must obtain the own property keys of the target object
by calling its [[OwnPropertyKeys]] internal method. Property attributes of the
target object must be obtained by calling its [[GetOwnProperty]] internal method.
OrdinaryOwnPropertyKeys ( O )
[...]
3. For each own property key P of O that is a String but is not an array index,
in ascending chronological order of property creation, do
a. Add P as the last element of keys.
