1.12 + ECMA Section: 11.13.2 Compound Assignment:+=
1.13 + Description:
1.14 +
1.15 + *= /= %= += -= <<= >>= >>>= &= ^= |=
1.16 +
1.17 + 11.13.2 Compound assignment ( op= )
1.18 +
1.19 + The production AssignmentExpression :
1.20 + LeftHandSideExpression @ = AssignmentExpression, where @ represents one of
1.21 + the operators indicated above, is evaluated as follows:
1.22 +
1.23 + 1. Evaluate LeftHandSideExpression.
1.24 + 2. Call GetValue(Result(1)).
1.25 + 3. Evaluate AssignmentExpression.
1.26 + 4. Call GetValue(Result(3)).
1.27 + 5. Apply operator @ to Result(2) and Result(4).
1.28 + 6. Call PutValue(Result(1), Result(5)).
1.29 + 7. Return Result(5).
