I want to store my radio button values in an object on local storage with index of the object as key of it. What should I do to make fix size array? Also I want to set that object as initial value of my state. I have tried some things, but it does not work out.

var obj = {'one': 1,'two': 2,'three': 3 };
localStorage.setItem('testObject', JSON.stringify(testObject));
var retrievedObject = localStorage.getItem('testObject');
console.log('retrievedObject: ', JSON.parse(retrievedObject));

I am making an quiz app in which I want to save my selected answers on localstorage but when i come to previous question to reset my answer and then go onto next question then i don't want new item added in my object.
This is how you make an array with the fix length 5 and all element as A.
const LEN = 5;
const arr = new Array(LEN).fill(A);
localStorage.setItem("ID", JSON.stringify(arr))
