Developing a nested JSON structure

Question

Developing a nested JSON structure

I'm struggling with a seemingly simple task of creating a JSON object. Despite my efforts, I can't seem to find the right information to guide me through it. Here is what I have so far:

var myJsonObject = new Object();
myJsonObject.context.applicationName = appName;
myJsonObject.context.ID = ID;
myJsonObject.context.domain = domain;
myJsonObject.context.production = "no";

myJsonObject.other.name = userName;
myJsonObject.other.date = userDate;

var myString = JSON.stringify(myJsonObject);

This is what I envision my JSON string should look like:

{
"context": {
   "applicationName":"example",
   "ID":"exampleID",
   "domain":"someDomain",
   "production","no"
 },
"other": {
   "name":"userName1",
   "date":"userDate1"
 }
}

Unfortunately, I keep encountering

myJsonObject.context is undefined

errors. I understand that this is due to not initializing it properly, but I'm at a loss on how to rectify this issue. Any guidance would be greatly appreciated.

I believe that myJsonObject.context needs to be initialized as another object before adding it to the original object as an array of objects. Is my assumption correct?

A crucial step is to initialize it as an object before proceeding, or alternatively you can assign the values directly on the initial line:

const newObj = {model : {} , type: {} };

It's important to mention that there is a more concise way to define your objects, as demonstrated below:

let myObject = {
    context: {
        appName,
        ID,
        domain,
        production: "no"
    },
    otherDetails: {
        userName,
        userDate
    }
};

It appears that initializing myJsonObject.context as another object is necessary

Affirmative

Subsequently, I simply include it in my original object

This step is typically done simultaneously

in the form of an array of objects

Negative. There is no indication of an array in that structure.

var myJsonObject = {};
myJsonObject.context = {};
myJsonObject.context.applicationName = appName;
