|
|
Description:
|
|
The production UnaryExpression : ++ UnaryExpression is evaluated as
|
|
follows:
|
|
|
|
1. Evaluate UnaryExpression.
|
|
2. Call GetValue(Result(1)).
|
|
3. Call ToNumber(Result(2)).
|
|
4. Add the value 1 to Result(3), using the same rules as for the +
|
|
operator (section 11.6.3).
|
|
