const localStorageHelper = {
    setItem(key, value) {
        localStorage.setItem(key, JSON.stringify(value));
    },
    getItem(key) {
        const item = localStorage.getItem(key);
        return item ? JSON.parse(item) : null;
    },
    removeItem(key) {
        localStorage.removeItem(key);
    }
};

// Usage Example
localStorageHelper.setItem('user', { name: 'John Doe', age: 30 });
console.log(localStorageHelper.getItem('user')); // { name: 'John Doe', age: 30 }
localStorageHelper.removeItem('user');

// Additional Notes:
// This helper abstracts the JSON parsing/stringifying. Always check for null and exceptions in real-world applications.
