| michael@0 | 9 | ECMA Section: 12.6.3 The for...in Statement |
| michael@0 | 10 | Description: |
| michael@0 | 11 | The production IterationStatement : for ( LeftHandSideExpression in Expression ) |
| michael@0 | 12 | Statement is evaluated as follows: |
| michael@0 | 13 | |
| michael@0 | 14 | 1. Evaluate the Expression. |
| michael@0 | 15 | 2. Call GetValue(Result(1)). |
| michael@0 | 16 | 3. Call ToObject(Result(2)). |
| michael@0 | 17 | 4. Let C be "normal completion". |
| michael@0 | 18 | 5. Get the name of the next property of Result(3) that doesn't have the |
| michael@0 | 19 | DontEnum attribute. If there is no such property, go to step 14. |
| michael@0 | 20 | 6. Evaluate the LeftHandSideExpression ( it may be evaluated repeatedly). |
| michael@0 | 21 | 7. Call PutValue(Result(6), Result(5)). PutValue( V, W ): |
| michael@0 | 22 | 1. If Type(V) is not Reference, generate a runtime error. |
| michael@0 | 23 | 2. Call GetBase(V). |
| michael@0 | 24 | 3. If Result(2) is null, go to step 6. |
| michael@0 | 25 | 4. Call the [[Put]] method of Result(2), passing GetPropertyName(V) |
| michael@0 | 26 | for the property name and W for the value. |
| michael@0 | 27 | 5. Return. |
| michael@0 | 28 | 6. Call the [[Put]] method for the global object, passing |
| michael@0 | 29 | GetPropertyName(V) for the property name and W for the value. |
| michael@0 | 30 | 7. Return. |
| michael@0 | 31 | 8. Evaluate Statement. |
| michael@0 | 32 | 9. If Result(8) is a value completion, change C to be "normal completion |
| michael@0 | 33 | after value V" where V is the value carried by Result(8). |
| michael@0 | 34 | 10. If Result(8) is a break completion, go to step 14. |
| michael@0 | 35 | 11. If Result(8) is a continue completion, go to step 5. |
| michael@0 | 36 | 12. If Result(8) is a return completion, return Result(8). |
| michael@0 | 37 | 13. Go to step 5. |
| michael@0 | 38 | 14. Return C. |
