How to reset Jasmine Spy object?

Question

Not able to find docs for resetting the Jasmine Spy object. If there is better way of using spy objects, please suggest.

// spec.js
import { mockService } from "./mockService"; // mockService = jasmine.createSpyObj(...)

describe('test', () => {
  beforeEach(function () {
    // NOTE: Following don't work

    // mockService.reset();
    // mockService.calls.reset();
    // mockService.method.calls.reset();
  });

  it('a', () => {
    mockService.fn();
    expect(mockService.fn).toHaveBeenCalledTimes(1);
  });

  it('b', () => {
    mockService.fn();
    expect(mockService.fn).toHaveBeenCalledTimes(1);
  });
});

It should work as expected.

Eg

const service = {
  fn() {},
};

const mockService = jasmine.createSpyObj(service, 'fn');

describe('test', () => {
  beforeEach(function () {
    mockService.fn.calls.reset();
  });

  it('a', () => {
    mockService.fn();
    expect(mockService.fn).toHaveBeenCalledTimes(1);
  });

  it('b', () => {
    mockService.fn();
    expect(mockService.fn).toHaveBeenCalledTimes(1);
  });
});

Incorrect way: spyObj.calls.reset()

Correct way: spyObj.spyMethod.calls.reset()

NOTE : calls.reset() is done for spy methods and not for spy object.
