| 9 ECMA Section: 12.6.3 The for...in Statement | |
| 10 Description: | |
| 11 The production IterationStatement : for ( LeftHandSideExpression in Expression ) | |
| 12 Statement is evaluated as follows: | |
| 13 | |
| 14 1. Evaluate the Expression. | |
| 15 2. Call GetValue(Result(1)). | |
| 16 3. Call ToObject(Result(2)). | |
| 17 4. Let C be "normal completion". | |
| 18 5. Get the name of the next property of Result(3) that doesn't have the | |
| 19 DontEnum attribute. If there is no such property, go to step 14. | |
| 20 6. Evaluate the LeftHandSideExpression (it may be evaluated repeatedly). | |
| 21 7. Call PutValue(Result(6), Result(5)). PutValue( V, W ): | |
| 22 1. If Type(V) is not Reference, generate a runtime error. | |
| 23 2. Call GetBase(V). | |
| 24 3. If Result(2) is null, go to step 6. | |
| 25 4. Call the [[Put]] method of Result(2), passing GetPropertyName(V) | |
| 26 for the property name and W for the value. | |
| 27 5. Return. | |
| 28 6. Call the [[Put]] method for the global object, passing | |
| 29 GetPropertyName(V) for the property name and W for the value. | |
| 30 7. Return. | |
| 31 8. Evaluate Statement. | |
| 32 9. If Result(8) is a value completion, change C to be "normal completion | |
| 33 after value V" where V is the value carried by Result(8). | |
| 34 10. If Result(8) is a break completion, go to step 14. | |
| 35 11. If Result(8) is a continue completion, go to step 5. | |
| 36 12. If Result(8) is a return completion, return Result(8). | |
| 37 13. Go to step 5. | |
| 38 14. Return C. | |
