description: Strict equality comparison of BigInt values
esid: sec-strict-equality-comparison
info: |
  1. If Type(x) is different from Type(y), return false.
  2. If Type(x) is Number or BigInt, then
    a. Return ! Type(x)::equal(x, y).

  sec-numeric-types-bigint-equal
  BigInt::equal (x, y)

    The abstract operation BigInt::equal with two arguments x and y of BigInt type returns true if x and y have the same mathematical integer value and false otherwise.
