You can loop through all the localStorage items and use the localStorage.key(index) to get the key and use it in localStorage.getItem to get the value.

for (let i = 0; i < localStorage.length; i++) {
    let key = localStorage.key(i);
    let val = localStorage.getItem(key);
}

You can use localStorage

Creating Entries

let key = 'Item 1';
localStorage.setItem(key, 'Value');

Reading Entries

let myItem = localStorage.getItem(key);

Updating Entries

localStorage.setItem(key, 'New Value');

Deleting Entries

localStorage.removeItem(key);

Clearing Everything

localStorage.clear();

You need to use localstorage.length that will return you the number of keys stored.

console.log("Keys stored", localStorage.length);

You can also iterate for all the keys stored in localstorage localstorage.key return the key name at this position

for (let i = 0; i < localStorage.length; i++) {
    let key = localStorage.key(i); // Will return the name of the key
    let val = localStorage.getItem(key); // will return the value
}

get length of local storage keys. returns number of keys stored

localStorage.length

Return the key name at this position

localStorage.key(id)

let n = localStorage.length;
    for(let i=0;i<n;i++){
        console.log("--->",localStorage.key(i));
    }
