What is the Differences between localStorage, sessionStorage, and cookies?

Comment

localStorage:
Purpose: Used to store data on the client side (within the user’s browser).
Capacity: Can store up to 10MB of data.
Persistence: Data remains even after the browser is closed.
Example: Storing user preferences (like light-dark mode settings) that persist across sessions.

sessionStorage:
Purpose: Also stores data on the client side, but only for the current session.
Capacity: Similar to localStorage (around 5MB per domain).
Persistence: Cleared when the user closes the browser or tab.
Example: Keeping temporary data during a single browsing session (e.g., form data).

Cookies:
Purpose: Used for small, persistent data across sessions.
Capacity: Each cookie can hold up to 4 Kb of data.
Persistence: Remains until explicitly deleted or expire at a certain time.
Example: Storing user authentication tokens or remembering login status.
