What is the process of utilizing Jasmine's toEqual(jasmine.objectContaining) functionality to compare arrays?

I am interested in comparing specific elements of arrays that are partially similar.

Is there a more efficient method than using a foreach loop alongside a nested

toEqual(jasmine.objectContaining)
?

Answer â„–1

Utilizing AngularJS alongside Jasmine version 3.3.1, I have achieved success implementing a similar structure:

it('modifies a property on each object within an array', () => {
  const result = service.updateObjects([{ prop: 'original' }, { prop: 'original' }]);
  expect(result).toEqual([
    jasmine.objectContaining({ prop: 'modified' }),
    jasmine.objectContaining({ prop: 'modified' })
  ]);
});

This approach proves to be more concise compared to multiple toEqual assertions.
