description: Left shift for non-primitive BigInt values
esid: sec-left-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::leftShift(lnum, rnum).
