|
|
Description:
|
|
|
|
11.3.2 Postfix decrement operator
|
|
|
|
The production MemberExpression : MemberExpression -- is evaluated as follows:
|
|
1. Evaluate MemberExpression.
|
|
2. Call GetValue(Result(1)).
|
|
3. Call ToNumber(Result(2)).
|
|
4. Subtract the value 1 from Result(3), using the same rules as for the -
|
|
operator (section 0).
|
|
5. Call PutValue(Result(1), Result(4)).
|
|
6. Return Result(3).
