I have this code that is trying to retrieve data from localstorage. However, nothing happens at all when it is run and there are no console errors.

    var score = localStorage.getItem('score') || 0;
    
    function save() {
    counter = localStorage.getItem('score', score)
    }

<body onload="save()">
        <p id="score">0</p>
        <img src="popcat1.png" alt="Invalid" id="popcat1">

I don't know I'm doing wrong and I want the score not to reset on refresh. Please tell me if there is a better way.

Local storage is not a complicated thing. There are only 4 basic operations.

Set data in localStorage:

localStorage.setItem('name', variable)

Get data from localStorage:

localStorage.getItem('name')

Remove from localStorage

localStorage.removeItem('name')

Remove all from localStorage

localStorage.clear()

In your code, you need to setItem first and than you can get the value.

Just use setItem on save rather than getItem:

let score = localStorage.getItem('score') || 0
function save() {
  localStorage.setItem('score', score)
  //           ^^^^^^^
}
