The following rules for IfStatement augment those in 13.6:
|
||
|
|
|

IfStatement[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]
