Expect.toBeEqual is failing when an attribute is a function

Question

I have a simple test using vitest that is comparing a simple array with single item with same array. Here is the code.

import '@testing-library/jest-dom'
import { describe, it, expect } from 'vitest';

describe('Simple Test', () => {
  it('Test simple assertion', () => {
    expect([
      {
        id: "key1",
        header: "key1",
        cell: (e) => e["key1"],  <== This is the problematic line
      },
    ]).toEqual([
      {
        id: "key1",
        header: "key1",
        cell: (e) => e["key1"],  <== This is the problematic line
      },
    ]);
  });
});

The issue I'm facing is that assertion is failing with following error. If I comment out the above cell attribute in each of the array, the assertion is succeeding.

AssertionError: expected [ Array(1) ] to deeply equal [ Array(1) ]
    at /Volumes/Code/Nexus-BCM/src/Nexus-UCM/test/react/widgets/ListWidget.test.tsx:53:8

Can anyone suggest how I can make this assertion succeed?
