I need to create a nested object that looks like this
var a = "example"
{Chatting : {a :{ 'id' :a}}}
I can't really find anything online, I tried the code below and its not working
myobj['Chatting'][a] = {
'id': a
}

1Your question is quite unclear. What are you trying to do, and how do you know that it's not working?hughes– hughes2017-03-13 04:24:57 +00:00Commented Mar 13, 2017 at 4:24

Describe what 'not working' is and what you are actually trying to accomplish. In the example you've listed, it's probably down to your indices not being literals.pvg– pvg2017-03-13 04:27:56 +00:00Commented Mar 13, 2017 at 4:27

To access the id property of the nested myObj you can try this:
var myObj={Chatting : {a :{ 'id' : 'a'}}};
alert(myObj.Chatting.a.id)
TO create a nested Object:
var Obj = { };
Obj["nestedObj"] = {};
Obj["nestedObj"]["nestedObj1"] = "value";
console.log(Obj);

At once:
var a = "example"
var obj = {Chatting : {a :{ 'id' :a}}};
console.log(obj);Step by step:
var a = "example"
var obj = {}; // create the object obj
obj.Chatting = {}; // create the sub-object Chatting of obj
obj.Chatting.a = {}; // create the sub-object a of Chatting
obj.Chatting.a.id = a; // set it's id to a
console.log(obj);

Your question is quite unclear. But i guess, you want get element a, right?
let a = {Chatting : {a :{ 'id' : 'a'}}};
console.log(a.Chatting.a);

i edited the question, i need to create the object not access it
attribute names cannot be objects. (string variables are fine)
var a = "example";
var myObj = {
Chatting: {
a: { // here it is assumes to be "a"
"id": a // here exapmle is being stored in to "id"
}
}
}
console.log(myObj["Chatting"]["a"])// will let you access it
Comments
var a = "example";
var obj = {Chatting : {a :{ 'id' :'a'}}};
Please note that in an object {key:value} key is a string not variable. I am defining here id:'a', which will output
console.log(obj['Chatting']['a']['id']); // 'a'
and adding variable to the object
obj['Chatting']['a'] = {'id':a};
which will output
console.log(obj['Chatting']['a']['id']); // 'example'
