6. If Initializer is present and v is undefined, then
a. Let defaultValue be the result of evaluating Initializer.
b. Let v be GetValue(defaultValue).
c. ReturnIfAbrupt(v).
6.2.3.1 GetValue (V)
1. ReturnIfAbrupt(V).
2. If Type(V) is not Reference, return V.
3. Let base be GetBase(V).
4. If IsUnresolvableReference(V), throw a ReferenceError exception.
