Add Auto Complete feature to JSON.stringfy method.

[EliaquimNascimento]

Hi!
Thanks for your extension on Visual Studio. It helps me a lot! ^^
I want to ask you if you can add the autocomplete feature in a case that I apply a global object to a local object, for example:

let globalObject = {
       hair: "black",
       eyes: "brown"
}

Game_System.prototype.initiate = function(){
         this._obj =  JSON.parse(JSON.stringfy(globalObject))
}

$gameSystem = new Game_System();

Inside my application, it works ok. But I really want it to work inside the visual studio code.
If I type:
globalObject .[it will autocomplete as property]

but in this case:
$gameSystem._obj.[it not autocomplete like a property]
