description: Non-strict inequality comparison of BigInt values
esid: sec-abstract-equality-comparison
info: |
  1. If Type(x) is the same as Type(y), then
    a. Return the result of performing Strict Equality Comparison 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.
