description: Variable-scoped binding is updated (IfStatement without an else clause in eval code)
esid: sec-functiondeclarations-in-ifstatement-statement-clauses
flags: [generated, noStrict]
info: |
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.3.3.3 Changes to EvalDeclarationInstantiation
[...]
b. 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.
iii. 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).
