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.
