description: Throws a TypeError if the this value is not a BigInt

  BigInt.prototype.toString ( [ radix ] )

  1. Let x be ? thisBigIntValue(this value).
  ...

  The abstract operation thisBigIntValue(value) performs the following steps:

  1. If Type(value) is BigInt, return value.
  2. If Type(value) is Object and value has a [[BigIntData]] internal slot, then
    ...
  3. Throw a TypeError exception.
