DeepEqualExcludingEvery isn't working properly on deeply nested Date Objects

[ThomasDenoncin]

Hey !

I noticed an issue with the deepEqualExcluding function.
Deeply nested date objects are not compared properly.
Here is my test case, with all tests should be failing :

import { assert, use } from 'chai';
import chaiExclude from 'chai-exclude';

use(chaiExclude);

describe('deepEqualExcludingEvery', () => {
    const today = new Date();
    const oldDay = new Date('1970-01-01T00:00:00.000Z');

    it('should compare two objects', () => {
        assert.deepEqualExcluding({ date: today }, { date: oldDay }, []);
    });
    it('should compare two arrays of objects without props', () => {
        assert.deepEqualExcludingEvery([{ date: today }], [{ date: oldDay }]);
    });
    it('should compare two arrays of objects', () => {
        assert.deepEqualExcludingEvery([{ date: today }], [{ date: oldDay }], []);
    });
});

Upon further inspection, I noticed this :
In file chai-exclude.js, on ligne 203, this._obj value is [{ date: {} }]

But even then, how comes line 152 - new Assertion(actual, message).excludingEvery(props).to.deep.equal(expected) is validating this comparison ?

Is that the intended behavior ?

Node version is 20.15.1
Packages are :

"chai": "5.1.1",
"chai-exclude": "3.0.0",

Best regards,
