Choosing a JSON item based on its numerical position rather than by its name

Question

Choosing a JSON item based on its numerical position rather than by its name

I am attempting to store a JSON object containing information in multiple languages. I am uncertain if the way I have implemented it is optimal, so any suggestions are appreciated.

My current issue is that I am unsure how to access the first language without knowing what language it is.

var Data = {

  "NameIntern": "Something intern",
  "en":  {
          "Name": "Some name",
          "ModuleOrder": "123,333,22" }
};

document.write(Data[1].Name);

I simply want to be able to access the second object; sometimes it's "en", sometimes it's "de".

Any tips would be greatly appreciated!

Looking for a JavaScript solution that's easy and efficient? Here's a great approach:

var keys = Object.keys(myData);

Next, store these keys in an array where you can access them using an index like so:

myData[keys[0]]

From here, feel free to use a loop or any other method you prefer!

Data is not structured as an array, so you cannot access it using Data[0]. Instead, you should access it like Data.en.

Since you mentioned that you are unsure about en or de, I recommend structuring the Data object in this way:

var Data = [{
    lang: "en",
    langData: {
        Name: "Some name"
    }
}]

let Information = {

  "InternName": "Internal thing",
  "fr":  {
          "Title": "Some title",
          "SectionOrder": "890,567,54"  }
};

let count = 0;
$.each(Information, function(identifier, value){
  count += 1;
  if (count == 2){
    // identifier represents the language, for instance in this scenario it's 'fr'
    console.log(identifier);
  }  
});

let username = (Data.en || Data.de || {})['Username'];

(Data.en || Data.de || {}) retrieves the value of Data.en or Data.de, if both do not exist, it returns an empty object to prevent script errors related to the Username property
()['Username'] is equivalent to myObject['Username'] or myObject.Username
the retrieved value is assigned to the variable username, which will be either a specific username or undefined

If additional languages are added, include them in the script - the first language found will be returned

let username = (Data.en || Data.de || Data.ru || Data.fr || {})['Username'];

To retrieve a list of property names from an object, you can use the Object.keys method:

const key = Object.keys(myData)[0];
console.log(myData[key]['Title']);   // "My Title"
