Description:
*= /= %= += -= <<= >>= >>>= &= ^= |=
11.13.2 Compound assignment ( op= )
The production AssignmentExpression :
LeftHandSideExpression @ = AssignmentExpression, where @ represents one of
the operators indicated above, is evaluated as follows:
1. Evaluate LeftHandSideExpression.
2. Call GetValue(Result(1)).
3. Evaluate AssignmentExpression.
4. Call GetValue(Result(3)).
5. Apply operator @ to Result(2) and Result(4).
6. Call PutValue(Result(1), Result(5)).
7. Return Result(5).
