JAVASCRIPT object to array conversion

I search on stackoverflow before post my question, but I didn't find any solution. I have an object like this : 

"{"COURRIERS":
     {"05. Juridique":
         [{"res_id":100,"type_label":"Plainte","subject":"test23","doctypes_first_level_label":"COURRIERS","doctypes_second_level_label":"05. Juridique","folder_level":2}]
     }
}"

And I need to access it like an array, in order to get the information like res_id etc..

How can I do this ?

Thanks in advance

Assuming that you won't have more than one object/array in each layer, this should get you what you need.

let obj = {
  "COURRIERS": {
    "05. Juridique": [{
      "res_id": 100,
      "type_label": "Plainte",
      "subject": "test23",
      "doctypes_first_level_label": "COURRIERS",
      "doctypes_second_level_label": "05. Juridique",
      "folder_level": 2
    }]
  }
}

let folder = Object.keys(obj)[0]
let type = Object.keys(obj[folder])[0]
let result = obj[folder][type][0]

console.log(result)

Something like that ?

(I insert the data inside a variable and print the wanted result with key index)

let obj = {
   "COURRIERS":{
      "05. Juridique":[
         {
            "res_id":100,
            "type_label":"Plainte",
            "subject":"test23",
            "doctypes_first_level_label":"COURRIERS",
            "doctypes_second_level_label":"05. Juridique",
            "folder_level":2
         }
      ]
   }
};

console.log(obj["COURRIERS"]["05. Juridique"][0]["res_id"]);

EDIT

You want to acess it with variable. For avoid bug, I strong recommend you to check if the variable value key exist in the array/object like : 

let folder = 'COURRIERS';

if(folder.indexOf(data) >= 0) { // folder.indexOf(data) = 0
// ... finish the job here :)
}
// indexOf return -1 if the value is not found

You can gain access to the data in multiple ways. The following below will help clarify some of the way you can access some of the data.

myObj.type              = "Dot syntax";
myObj.type              = "Dot syntax";
myObj["date created"]   = "String with space";
myObj[str]              = "String value";
myObj[rand]             = "Random Number";
myObj[obj]              = "Object";
myObj[""]               = "Even an empty string";

For your problem you can use the following 

var x = { 
 "COURRIERS":{
  "05. Juridique":[
     {
        "res_id":100,
        "type_label":"Plainte",
        "subject":"test23",
        "doctypes_first_level_label":"COURRIERS",
        "doctypes_second_level_label":"05. Juridique",
        "folder_level":2
     }
  ]
}};
console.log(x['COURRIERS']['05. Juridique'][0].res_id)
