[Bug]: toStrictEqual doesn't work on simple arrays returned by C++ addon with node-api

[CMCDragonkai]

Version

27.3.1

Steps to reproduce

Clone MatrixAI/TypeScript-Demo-Lib#38. Run nix-shell to enter into the development environment.

Go to src/native/index.cpp.

NAPI_METHOD(createArr) {
  // Create arr with length of 1
  napi_value arr;
  NAPI_STATUS_THROWS(napi_create_array_with_length(env, 1, &arr))
  // Set the value on the arr
  napi_value value;
  NAPI_STATUS_THROWS(napi_create_double(env, 0.5, &value));
  NAPI_STATUS_THROWS(napi_set_element(env, arr, 0, value))
  return arr;
}

This native function just creates an JS array, and sets 5 to it. Basically [5].

Now in jest, go to tests/native.test.ts.

Test this:

    expect(native.createArr()).toEqual([0.5]);

Expected behavior

I would expect [0.5] to be [0.5].

Actual behavior

It says: Received: serializes to the same string.

In fact, you can test it like:

    const arr = native.createArr();
    expect(arr[0]).toStrictEqual(0.5);

And this does work.

Additional context

Actually this also applies to objects too. And I tested that this also occurs with node's assert.deepStrictEqual. So there must be some difference between objects created inside C++ vs objects created in JS-land.

This applies to node Buffer as well.
