Description

Missing coverage:

  1. this value capturing objects with an [[BigIntData]] internal. (e.g.: BigInt.prototype.toString.call(Object(1n))).
  2. ToInteger coercions and abrupt completions from radix.
  3. Observable variants for the same this value using different radix, as long as the implementation defined spec permits.

Contributor guide

Research direction
Examine the missing coverage areas: (1) this value capturing objects with [[BigIntData]] internal, (2) ToInteger coercions and abrupt completions from radix, (3) observable variants for different radix values. Write test cases that cover these scenarios for BigInt.prototype.toString.
