// Retrieve data from localStorage

const getUser = JSON.parse(localStorage.getItem('setNameKey')) || [];

​

// Perform operations with getUser array

console.log(getUser); // Outputs the retrieved data or an empty array if 'setNameKey' doesn't exist

​

// Modify getUser array if needed

getUser.push({ name: 'Alice', age: 25 });

​

// Save the modified data back to localStorage

localStorage.setItem('setNameKey', JSON.stringify(getUser));

​

// Now 'setNameKey' contains the modified data
