Can you use JSON.stringify on an array with objects? [closed]

I have this code:

let myArray= [{
    gained: 0,
    lost: 0
}];

localStorage.setItem('allPoints', JSON.stringify(myArray));

This works fine but if I want to parse it

localStorage.getItem('allPoints', JSON.parse(allPoints));

I get following error:

Uncaught SyntaxError: “[object Object]” is not valid JSON

Can’t you parse an array like this? Is there a way around this?

Answer

You definitely can.

You only got it a bit wrong with getItem.

It should be:

JSON.parse(localStorage.getItem("allPoints"))

You first need to retrieve the value. You might want to check also https://developer.mozilla.org/en-US/docs/Web/API/Storage/getItem.

And then you apply JSON.parse
