SuperProperty evaluation when "this" binding has not been initialized
|
|
info: |
|
|
1. Let propertyKey be StringValue of IdentifierName.
|
|
2. If the code matched by the syntactic production that is being evaluated is
|
|
strict mode code, let strict be true, else let strict be false.
|
|
3. Return ? MakeSuperPropertyReference(propertyKey, strict).
|
|
|
|
12.3.5.3 Runtime Semantics: MakeSuperPropertyReference
|
|
|
|
1. Let env be GetThisEnvironment( ).
|
|
2. If env.HasSuperBinding() is false, throw a ReferenceError exception.
|
|
3. Let actualThis be ? env.GetThisBinding().
|
|
|
|
8.1.1.3.4 GetThisBinding
|
|
|
|
1. Let envRec be the function Environment Record for which the method was
|
|
invoked.
|
|
2. Assert: envRec.[[ThisBindingStatus]] is not "lexical".
|
|
3. If envRec.[[ThisBindingStatus]] is "uninitialized", throw a ReferenceError
|
|
exception.
