| 12 | IfStatement[Yield, Return]: |
| 13 | if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield] else Statement[?Yield, ?Return] |

| 22 | b. When the FunctionDeclaration f is evaluated, perform the following steps |

| 25 | i. Let genv be the running execution context's VariableEnvironment. |
| 26 | ii. Let genvRec be genv's EnvironmentRecord. |
| 27 | iii. Let benv be the running execution context's LexicalEnvironment. |
| 28 | iv. Let benvRec be benv's EnvironmentRecord. |
| 29 | v. Let fobj be ! benvRec.GetBindingValue(F, false). |
| 30 | vi. Perform ? genvRec.SetMutableBinding(F, fobj, false). |
| 31 | vii. Return NormalCompletion(empty). |
