How do i compare 2 arrays returning different results:

responseFields=[
  { field: 'PHONE', required: true },
  { field: 'COMPANY', required: true },
  { field: 'MOBILE', required: true },
  { field: 'COUNTRY', required: true }
]
eventFields=AdditionalFields {
  company: BoolValue { value: true },
  phone: BoolValue { value: true },
  mobile: BoolValue { value: true },
  country: BoolValue { value: true }
}

following is what i tried to compare each field but it failed

for (const { field } of responseFields) {
     expect(field).to.eql(Object.keys(eventFields)[field]);
     }
