Here's a step-by-step guide on how to store objects in HTML5 localStorage/sessionStorage:

1. Create an object that you want to store.

const user = {
  name: 'John',
  age: 30,
  email: 'john@example.com'
};

2. Convert the object to a JSON string using the JSON.stringify() method.

javascript
const userJSON = JSON.stringify(user);

3. Store the JSON string in localStorage or sessionStorage using the setItem() method.

javascript
localStorage.setItem('user', userJSON);

4. To retrieve the stored object, use the getItem() method to retrieve the JSON string from localStorage or sessionStorage.

javascript
const storedUserJSON = localStorage.getItem('user');

5. Convert the JSON string back to an object using the JSON.parse() method.

javascript
const storedUser = JSON.parse(storedUserJSON);

6. You can now use the retrieved object just like any other object.

console.log(storedUser.name); // 'John'

That's it! With these steps, you can store and retrieve objects in HTML5 localStorage or sessionStorage using JSON serialization.
