toIncludeSameMembers output is hard to understand

[rluvaton]

Currently, if you have a test like this:

it('example', () => {
	const expected = Array.from({ length: 1000 }, (_, i) => ({
		i,
		value: 'expected'
	}));
	const actual = [...expected];
	const tmp = actual[200];
	actual[200] = actual[201];
	actual[201] = { ...tmp, value: 'hope you find me' };

	expect(actual).toIncludeSameMembers(expected);
});

You will get an error like this:

Error as text

   expect(received).toIncludeSameMembers(expected)

    Expected list to have the following members and no more:
      [{"i": 0, "value": "expected"}, {"i": 1, "value": "expected"}, {"i": 2, "value": "expected"}, {"i": 3, "value": "expected"}, {"i": 4, "value": "expected"}, {"i": 5, "value": "expected"}, {"i": 6, "value": "expected"}, {"i": 7, "value": "expected"}, {"i": 8, "value": "expected"}, {"i": 9, "value": "expected"}, …]
    Received:
      [{"i": 0, "value": "expected"}, {"i": 1, "value": "expected"}, {"i": 2, "value": "expected"}, {"i": 3, "value": "expected"}, {"i": 4, "value": "expected"}, {"i": 5, "value": "expected"}, {"i": 6, "value": "expected"}, {"i": 7, "value": "expected"}, {"i": 8, "value": "expected"}, {"i": 9, "value": "expected"}, …]

      410 |             actual[201] = { ...tmp, value: 'hope you find me' };
      411 |
    > 412 |             expect(actual).toIncludeSameMembers(expected);
          |                            ^
      413 |     });

which is very hard to understand so I would like to get something like this:

Error as text

    expect(received).toIncludeSameMembers(expected)

    - Expected  - 1
    + Received  + 1

Until and if the related PR gets merged I created an npm package with that matcher and the better output:
