ECMA Section: 11.4.4 Prefix increment operator
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).
5. Call PutValue(Result(1), Result(4)).
6. Return Result(4).
