How do I use localStorage to remember a user’s name

This code has been checked for errors and none were detected. But, when it runs, it alerts null.

For Sololearners my code bit: https://code.sololearn.com/WOv1cF0EewdB/?ref=app

Why is this?*

window.onload = function() {

let reload_interval= setInterval(rel, 120000);

if (localStorage.getItem('visit') !== true) { 


    let username = prompt('Enter your name:');

    if (confirm('Do you want to be known as ' + username + ' from now on?')) {

        localStorage.setItem('name', username);

    } else {

        username = prompt('OK then, enter your name:');

        if (confirm('Do you want to be known as ' + username + 'from now on?')) {

            localStorage.setItem('name', username);

        }

    }

    localStorage.setItem('visit', true);

}

if (localStorage.getItem('visit') === true) {

    document.getElementById('p').innerHTML = localStorage.getItem('name');
    
     alert('Hello, ' + localStorage.getItem('name'));

}


};

function clearLocalStorage() {
if (confirm('Do you want to clear current username data?')) {
  localStorage.clear();
    alert('Cleared');
}
}

*jQuery answers are OK

Answer

You are not getting a hello alert is because you are checking getItem‘s return value with === true and !== true.

setItem will convert your value to string, so localStorage.getItem('visit') === true will never be true

If you want to check if the user has visited the page, you should use === "true"(visited) and !== "true"(not visited) since it returns string.
