Generate one HTML from API based on the object key language and their value

I have an API request and I'm generating a HTML content from its data using .map();.

The issue I'm facing is that in the array of objects I have keys that are showing content in one language or another. I need to display specific keys in mapped HTML based on the language of the page.

Example of object key: UserFromRegEN: "content in EN" for English or UserFromRegEN: "contenu en français" for French.

My way of solving this isn't the DRY-est and there's some repeating code.

Please check below existing code and let me know what would be a better solution in this case. I would like to avoid generating a long HTML because of different language content in the keys. Any advices are welcomed! Thanks!

JavaScript:
// Find page language in URL
const findUrl = window.location.href;

const regex = /\.eu\/(\w{2})\//;
const match = regex.exec(findUrl);

const resultLangUrl = match && match[1];
let pageLang = resultLangUrl.toUpperCase();

let language = pageLang.includes("EN");
let pickContainer = document.querySelector('#container');

// deleting keys not coresponding to page language from the objects
//ex: page language is EN, delete all FR keys
if (pageLang === true) {
    data.forEach(object => {
        delete object['UserFromRegFR']
        delete object['UserFromCityFR']
        delete object['UserFromStreetFR']
    });

    //generate html for EN
    const generateHtmlEN = data.map(test => {
        return `<p>${test.UserFromRegEN}</p>
                <p>${test.UserFromCityEN}</p>
                <p>${test.UserFromStreetEN}</p>`
    }).join('');

    pickContainer.insertAdjacentHTML('afterbegin', generateHtmlEN);

} else {
    data.forEach(object => {
        delete object['UserFromRegEN']
        delete object['UserFromCityEN']
        delete object['UserFromStreetEN']
    });

    //generate html for FR
    const generateHtmlFR = data.map(test => {
        return `<p>${test.UserFromRegFR}</p>
                <p>${test.UserFromCityFR}</p>
                <p>${test.UserFromStreetFR}</p>`
    }).join('');

    pickContainer.insertAdjacentHTML('afterbegin', generateHtmlFR);
}

It's a design problem with your language Class,
'fr' or 'en' must be one parameter for a big array of language.
then you apply to your page the language in array you want.

the functions : myfunctionEN , myfunctionFR ... are lots of code because they are far from the good thing to do.

if you have 50 language to use , will you write 50 functions for languages one by one ?
no, you'll use arrays of contents.

_fr = ["bonjour",,,,"utilisateur",,"Comment ça va ?"," le monde"];
_en = ["Hello",,,,"User",,"How are you ?","World"];

function load_lang(language){ for(;;) ....;}

Thanks for the idea! I asked about it somewhere else and nobody was able to give an out of the box solution for this situation.
