+description: Extension not observed when creation of variable binding would produce an early error (Block statement) (IfStatement without an else clause in function 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.3.3.1 Changes to FunctionDeclarationInstantiation

+ [...]
+ ii. If replacing the FunctionDeclaration f with a VariableStatement that
+ has F as a BindingIdentifier would not produce any Early Errors for
+ func and F is not an element of BoundNames of argumentsList, then
