LocalStorage of JSON not working Jquery

I have a JSON array in Jquery that I am trying to save to localStorage for later use, but for some reason, whenever I try and save it, it comes up with an error that the object is not defined. Here is my current code:

localStorage.setItem("Jsonobject", JSON.stringify(json));

        var jsonobject = JSON.parse(localStorage.getItem(Jsonobject));

The error specifically states "Jsonobject is not defined" even though I just defined it in the line above. I have tried "Jsonobject" with single and double quotes and they both come up with the same error. I have followed the instructions on this page, https://www.smashingmagazine.com/2010/10/local-storage-and-how-to-use-it/, but it doesn't seem to be working for some reason.

The error happens because you do not put "Jsonobject" in quotation marks then the interpreter of JS assumes that you are referring to a variable and since it does not exist the variable, the interpreter tells you that it is not defined

Error: localStorage.getItem(Jsonobject)

Correct: localStorage.getItem('Jsonobject')

or

var itemKey = 'Jsonobject';
// Setting value
localStorage.setItem(itemKey, JSON.stringify(json));
// Getting value
var json = JSON.parse(localStorage.getItem(itemKey));

In getItem() you need to quote your key 'getItem('Jsonobject')'
