description: Unsigned right shift always throws for non-primitive BigInt values
esid: sec-unsigned-right-shift-operator-runtime-semantics-evaluation
info: |
ShiftExpression : ShiftExpression >>> AdditiveExpression
1. Let lref be the result of evaluating ShiftExpression.
2. Let lval be ? GetValue(lref).
3. Let rref be the result of evaluating AdditiveExpression.
4. Let rval be ? GetValue(rref).
5. Let lnum be ? ToNumeric(lval).
6. Let rnum be ? ToNumeric(rval).
7. If Type(lnum) does not equal Type(rnum), throw a TypeError exception.
8. Let T be Type(lnum).
9. Return T::unsignedRightShift(lnum, rnum).
Note: BigInt::unsignedRightShift always throws a TypeError
