Using LocalStorage and SessionStorage in JavaScript

LocalStorage and SessionStorage allow storing data in the browser.

1. LocalStorage

Data persists even after browser closes.

localStorage.setItem('name', 'John');

2. SessionStorage

Data is cleared when the session ends.

sessionStorage.setItem('token', 'abc123');

3. Use Cases

• Remembering user preferences
• Storing temporary auth tokens

Conclusion

These APIs provide easy client-side storage without backend calls.
