[JasminePRA]

Pull Request

Description

• Provides three methods: getItem, setItem, and removeItem
• Handles JSON parsing/stringifying automatically
• Returns null for non-existent keys instead of throwing errors

import useLocalStorage from './hooks/useLocalStorage';

const MyComponent = () => {
  const { getItem, setItem, removeItem } = useLocalStorage();
  
  // Store complex objects
  setItem('user', { name: 'John', age: 30 });
  
  // Retrieve and auto-parse
  const user = getItem('user'); // Returns parsed object or null
  
  // Clean up
  removeItem('user');
};
