description: Assignment Operator evaluates the value prior validating a SuperProperty's reference (null)

# 13.15.2 Runtime Semantics: Evaluation
AssignmentExpression : LeftHandSideExpression = AssignmentExpression
1. If LeftHandSideExpression is neither an ObjectLiteral nor an ArrayLiteral,
then
a. Let lref be the result of evaluating LeftHandSideExpression.
[...]
e. Perform ? PutValue(lref, rval).
# 6.2.4.5 PutValue ( V, W )
[...]
5. If IsPropertyReference(V) is true, then
a. Let baseObj be ? ToObject(V.[[Base]]).
