| AssignmentExpression : LeftHandSideExpression AssignmentOperator AssignmentExpression |
| 1. Let _lref_ be the result of evaluating |LeftHandSideExpression|. |
| 2. Let _lval_ be ? GetValue(_lref_). |
| ... |
| 7. Let _r_ be ApplyStringOrNumericBinaryOperator(_lval_, _opText_, _rval_). |
| 8. Perform ? PutValue(_lref_, _r_). |
| 9. Return _r_. |

| 1. Let _baseReference_ be the result of evaluating |MemberExpression|. |
| 2. Let _baseValue_ be ? GetValue(_baseReference_). |
| 3. Let _fieldNameString_ be the StringValue of |PrivateIdentifier|. |
| 4. Return ! MakePrivateReference(_baseValue_, _fieldNameString_). |
