    AssignmentExpression:

    1. Let lref be the result of evaluating LeftHandSideExpression.
    2. Let lval be ? GetValue(lref).
    3. Let lbool be ! ToBoolean(lval).
    4. If lbool is false, return lval.
    5. Let rref be the result of evaluating AssignmentExpression.
    6. Let rval be ? GetValue(rref).
    7. Perform ? PutValue(lref, rval).
    8. Return rval.
