Compare array of object with an array

I have a request

const request=additionalFields: [
    { field: 'PHONE', required: true },  
    { field: 'COMPANY', required: true },
    { field: 'MOBILE', required: true }, 
    { field: 'COUNTRY', required: true } 
  ]

the response i am getting is this

"additionalFields":
{
    'PHONE':true,
    'COMPANY':true,
    'MOBILE':true,
    'COUNTRY':true
}

i am not sure how to compare them. i kind of wrote something but even to me it looks wrong

const fields = request["additionalFields"];
    
    for (let i = 0, len = fields.length; i < len; i++) {
      expect(request.additionalFields[i].required).to.eql(
        response.additionalFields
      );

You can use the for...of syntax to do this.

Here's the documentation.

const request = {
  additionalFields: [
    { field: 'PHONE', required: true },  
    { field: 'COMPANY', required: true },
    { field: 'MOBILE', required: true }, 
    { field: 'COUNTRY', required: true } 
  ]
};

const response = {
  additionalFields: {
    PHONE:true,
    COMPANY:true,
    MOBILE: true,
    COUNTRY:true
  }
}

const requestFields = request['additionalFields'];
const responseFields = response['additionalFields'];

for(const { required, field } of requestFields) {
    expect(required).to.eql(responseFields[field]);
}

You should loop over each field detail in the request and compare the value against the response. Here you go:

const request = {
    additionalFields: [
        { field: 'PHONE', required: true },
        { field: 'COMPANY', required: true },
        { field: 'MOBILE', required: true },
        { field: 'COUNTRY', required: true },
    ],
};

const response = {
    additionalFields: {
        PHONE: true,
        COMPANY: true,
        MOBILE: true,
        COUNTRY: true,
    },
};

for (let f of request.additionalFields) {
    // Observe f is like { field:'PHONE', required: true }
   // Next two lines are just for test, please remove and uncomment last one in your use case.
    const comparisonResult = f.required === response.additionalFields[f.field];
    console.log(`for field ${f.field}, It's ${comparisonResult}`);
    // expect(f.required).to.eql(response.additionalFields[f.field]);
}

You can further improve readability by using destructuring, drop a comment if you want to see that.

Here's another way. Just filter out anything that doesn't match up, then you'll have an array of differences if there are any.

const request={
additionalFields: [
    { field: 'PHONE', required: true },  
    { field: 'COMPANY', required: true },
    { field: 'MOBILE', required: true }, 
    { field: 'COUNTRY', required: true } 
  ]
 }

const incoming = {
  "additionalFields": {
    'PHONE': true,
    'COMPANY': true,
    'MOBILE': false,
    'COUNTRY': true
  }
}

let differences = request.additionalFields.filter(f => incoming.additionalFields[f.field] !== f.required)
console.log(differences)

You need to dereference the response.additionalFields object using the value of field from each entry in request.additionalFields. Something like

for(const { field, required } of request.additionalFields) {
    expect(required).to.eql(
        response.additionalFields[field]
      );
}

    const request = [
        { field: 'PHONE', required: true },  
        { field: 'COMPANY', required: true },
        { field: 'MOBILE', required: true }, 
        { field: 'COUNTRY', required: true } 
      ]

    const response = {"additionalFields":
    {
        'PHONE':true,
        'COMPANY':true,
        'MOBILE':true,
        'COUNTRY':true
    }}
    
    for (const [key, value] of Object.entries(response['additionalFields'])) {
       const {required, field} = request.find(({field}) => key === field);
        if(required === value) {  // here you can compare
            console.log(key, field, value);  
        }
    }
