Let’s say you have a Fruit object:

var fruit = {id: 1, value: 100, description: "Some text."};

 

Now, when you call myLocalStorage#setValue you can take the id as the key and the whole object as the value.

With JSON.stringify(object) you get a JSON string of the object.

JSON.stringify(fruit);
=> '{"id":1,"value":100,"description":"Some text."}'

 

So we have

myLocalStorage.setValue(fruit.id, JSON.stringify(fruit));

 

Now, in order to reconstruct your fruit from JSON, simply retrieve the value and call JSON.parse on the string:

var JSONifiedFruit = myLocalStorage.getValue(1);
var fruit = JSON.parse(JSONifiedFruit);

 

I hope it helps!
