description: Extension is observed when creation of variable binding would not produce an early error (try statement) (IfStatement with a declaration in the second statement position in the global scope)
|
|
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.3.3.2 Changes to GlobalDeclarationInstantiation
|
|
|
|
[...]
|
|
b. If replacing the FunctionDeclaration f with a VariableStatement that has
|
|
F as a BindingIdentifier would not produce any Early Errors for script,
|
|
then
|
|
[...]
|
|
|
|
B.3.5 VariableStatements in Catch Blocks
|
|
|
|
[...]
|
|
- It is a Syntax Error if any element of the BoundNames of CatchParameter
|
|
also occurs in the VarDeclaredNames of Block unless CatchParameter is
|
|
CatchParameter:BindingIdentifier and that element is only bound by a
|
|
VariableStatement, the VariableDeclarationList of a for statement, or the
|
|
ForBinding of a for-in statement.
