| ECMA Section: 12.6.3 The for...in Statement |
| Description: |
| The production IterationStatement : for ( LeftHandSideExpression in Expression ) |
| Statement is evaluated as follows: |
| |
| 1. Evaluate the Expression. |
| 2. Call GetValue(Result(1)). |
| 3. Call ToObject(Result(2)). |
| 4. Let C be "normal completion". |
| 5. Get the name of the next property of Result(3) that doesn't have the |
| DontEnum attribute. If there is no such property, go to step 14. |
| 6. Evaluate the LeftHandSideExpression ( it may be evaluated repeatedly). |
| 7. Call PutValue(Result(6), Result(5)). PutValue( V, W ): |
| 1. If Type(V) is not Reference, generate a runtime error. |
| 2. Call GetBase(V). |
| 3. If Result(2) is null, go to step 6. |
| 4. Call the [[Put]] method of Result(2), passing GetPropertyName(V) |
| for the property name and W for the value. |
| 5. Return. |
| 6. Call the [[Put]] method for the global object, passing |
| GetPropertyName(V) for the property name and W for the value. |
| 7. Return. |
| 8. Evaluate Statement. |
| 9. If Result(8) is a value completion, change C to be "normal completion |
| after value V" where V is the value carried by Result(8). |
| 10. If Result(8) is a break completion, go to step 14. |
| 11. If Result(8) is a continue completion, go to step 5. |
| 12. If Result(8) is a return completion, return Result(8). |
| 13. Go to step 5. |
| 14. Return C. |
