Parse nested JSON Response Javascript

Question

I know there are several threads on this subject but I've looked through over 30 threads without success. I have managed to parse a JSON response so it looks like this:

   {
    "1": {
       "id": "1",
       "name": "Fruit",
       .
       .
       .
       "entities": {
          "1": {
            "id": "1",
            "name": "blue bird",
       .
       .
       .
       "status": "1"
    },
   "2": {

using this code

    let json = JSON.parse(body);
    console.log(json);

Now I want to access the "id", "name" etc. AND the "id" and "name" for the "entities" tag. So far I have tried:

    console.log(json[0]);
    console.log(json.id);

which both returns undefined

I have also tried

    console.log(json[0].id);

which gives an error

Any ideas?

looks like your first key is json["1"]

In this instance, your first key is 1, so you can access it with json[1].

const json = {
  "1": {
    "id": "1",  
    "name": "Fruit"
  },
  "2": {
    "id": "2",  
    "name": "Veggies"
  }
};

console.log(json[1]);

In this json, you can reach the id by

json.1.id

But I think that first of all your json is not correctly written, you should have something like

{ 
"elements": [
    { "id" : 1, "name" : "fruit" },
    { "id" : 2, "name" : "vegetable" }
]
}

like that, json.elements is a collection/array, and you can loop, count, or any other things you will not be able to do because your json looks like a super heavy list of different properties ( he doesn't know that json.1 and json.2 are the same type of objects.

const jsonData = JSON.parse(body);

for (const i in jsonData) {
  for (const j in jsonData[i]) {
    console.log('${i}: ${jsonData[i][j]}');
  }
}
