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.
