JSONata to alter array of object and rename name keys

Trying to alter an array of object with JSONata, addresses names need to be altered and some items are not used at all, what I can tell is if I alter the array it make groups them into an individual array like lineOne would be [{"MY HOUSE1","SUITE 11-1111"}] and the if function does not work the way I would assume it should.

Source:

{
    "customers": [
        {
            "title": "DR.",
            "firstName": "FRED",
            "middleName": "L.",
            "lastName": "BEERMAN",
            "suffix": "MR.",
            "addresses": [
                {
                    "addressLine1": "MY HOUSE1",
                    "addressLine2": "1366 ELM LANE",
                    "city": "EAST GREENBUSH",
                    "state": "NY",
                    "zip": "800131234",
                    "county": "SCHENECTADY",
                    "countryCode": "US",
                    "addressType": "RESIDENCE",
                    "sendMail": true,
                    "key": "0"
                },
                {
                    "addressLine1": "SUITE 11-1111",
                    "addressLine2": "1366 ELM LANE",
                    "city": "EAST GREENBUSH",
                    "state": "NY",
                    "zip": "12061",
                    "county": "SCHENECTADY",
                    "countryCode": "US",
                    "addressType": "SHIPPING",
                    "sendMail": true,
                    "key": "1"
                }
            ]
        }
    ]
}

Expectation:

{
    "customers": [
        {
        "title": "DR.",
        "givenName": "FRED",
        "middleName": "L.",
        "familyName": "BEERMAN",
        "nameSuffix": "MR.",
        "addresses": [
            {
            "addressType": "RESIDENCE",
            "lineOne": "MY HOUSE1",
            "lineTwo": "1366 ELM LANE",
            "cityName": "EAST GREENBUSH",
            "stateOrProvinceCountrySubDivisionId": "NY",
            "postCode": "800131234",
            "countyCountrySubDivision": "SCHENECTADY",
            "countryId": "US",
            "privacy": [
                        {
                            "okToContact": true
                        }
                    ]
                },
                {
                "addressType": "SHIPPING",
                "lineOne": "SUITE 11-1111",
                "lineTwo": "1366 ELM LANE",
                "cityName": "EAST GREENBUSH",
                "stateOrProvinceCountrySubDivisionId": "NY",
                "postCode": "800131234",
                "countyCountrySubDivision": "SCHENECTADY",
                "countryId": "US",
                "privacy": [
                        {
                            "okToContact": true
                        }
                    ]
                }
            ]
        }
    ]
}

What I have tried:

"customerParty": {
	"givenName": customers.firstName,
	"middleName": customers.middleName,
	"familyName": customers.lastName,
	"title": customers.title,
	"salutation": customers.title,
	"addresses":[
		customers.addresses.$each(function($value, $key) {
			{ 
				$key ? 'addressType' : 'addressType:' $value,
				$key ? 'addressLine1' : 'lineOne:' $value,
				$key ? 'addressLine2' : 'lineTwo:' $value,
				$key ? 'city' : 'cityName:' $value,
				$key ? 'countryCode' : 'countryId:' $value,
				$key ? 'zip' : 'postCode:' $value,
				$key ? 'state' : 'stateOrProvinceCountrySubDivisionId:' $value,
				$key ? 'county' : 'countyCountrySubDivision:' $value,
				$key ? 'sendMail' : '"privacy": [{"okToContact": $value}]:' ,
			}
			}) ~> $merge()
		]
	}

Also

"address":[
	{
		"addressType": customers.addresses.addressType,
		"lineOne": customers.addresses.addressLine1,
		"lineTwo": customers.addresses.addressLine2,
		"cityName": customers.addresses.city,
		"countryId": customers.addresses.countryCode,
		"postCode": customers.addresses.zip,
		"stateOrProvinceCountrySubDivisionId": customers.addresses.state,
		"countyCountrySubDivision": customers.addresses.county,
		"privacy": [
			{
				"okToContact": customers.addresses.sendMail
			}
		]
	}
]

You can use the map operator like this:

{
    "customerParty": {
        "givenName": customers.firstName,
        "middleName": customers.middleName,
        "familyName": customers.lastName,
        "title": customers.title,
        "salutation": customers.title,
        "addresses": customers.addresses.{
            "addressType": addressType,
            "lineOne": addressLine1,
            "lineTwo": addressLine2,
            "cityName": city,
            "countryId": countryCode,
            "postCode": zip,
            "stateOrProvinceCountrySubDivisionId": state,
            "countyCountrySubDivision": county,
            "privacy": [{ "okToContact": sendMail }]
        }
    }
}
