The following rules for IfStatement augment those in 13.6:
|
|
|
|
IfStatement[Yield, Return]:
|
|
if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield] else Statement[?Yield, ?Return]
|
|
if ( Expression[In, ?Yield] ) Statement[?Yield, ?Return] else FunctionDeclaration[?Yield]
|
|
if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield] else FunctionDeclaration[?Yield]
|
|
if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield]

B.3.3.2 Changes to GlobalDeclarationInstantiation

|
[...]
|
|
c. When the FunctionDeclaration f is evaluated, perform the following steps
|
|
in place of the FunctionDeclaration Evaluation algorithm provided in
|
|
14.1.21:
|
|
|
|
i. Let genv be the running execution context's VariableEnvironment.
|
|
ii. Let genvRec be genv's EnvironmentRecord.
|
|
ii. Let benv be the running execution context's LexicalEnvironment.
|
|
iv. Let benvRec be benv's EnvironmentRecord.
|
|
v. Let fobj be ! benvRec.GetBindingValue(F, false).
|
|
vi. Perform ? genvRec.SetMutableBinding(F, fobj, false).
|
|
vii. Return NormalCompletion(empty).
