Assign variable content to object property name

I want to create a json object in node.js that looks like this;

{ WantThisName: { property_length: 8 } }

Here is my code;

var property_name = "WantThisName"
var length = 8;

var Obj_bin;
Obj_bin= {property_name: {property_length:length} };
console.log (Obj_bin);

The console output is;

{ property_name: { property_length: 8 } }

The problem lies with property_name not getting the contents of the variable property_name.

You can use computed (dynamic) property names:

> foo = "foozz"
'foozz'
> {[foo]: 42}
{ foozz: 42 }

They're part of the Enhanced Object Literals of es2015 (https://github.com/lukehoban/es6features#enhanced-object-literals).

For your example:

> var property_name = "WantThisName";
var property_name = "WantThisName";
undefined
> var length = 8;
undefined
> {[property_name]: { property_length: length}}
{ WantThisName: { property_length: 8 } }
>
