description: Non-strict equality comparison of BigInt values and non-primitive objects
esid: sec-abstract-equality-comparison
info: |
  10. If Type(x) is either String, Number, BigInt, or Symbol and Type(y) is Object, return the result of the comparison x == ? ToPrimitive(y).
  11. If Type(x) is Object and Type(y) is either String, Number, BigInt, or Symbol, return the result of the comparison ? ToPrimitive(x) == y.

  then after the recursion:

  1. If Type(x) is the same as Type(y), then
    a. Return the result of performing Strict Equality Comparison x === y.
  ...
  6. If Type(x) is BigInt and Type(y) is String,
    a. Let n be StringToBigInt(y).
    b. If n is NaN, return false.
    c. Return the result of x == n.
  7. If Type(x) is String and Type(y) is BigInt, return the result of y == x.
