| description: Variable-scoped binding is updated following evaluation (IfStatement with a declaration in both statement positions 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). |
