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

27 i. Perform ! varEnvRec.CreateMutableBinding(F, true).
28 ii. Perform ! varEnvRec.InitializeBinding(F, undefined).
