What other ways of storing data in the browser do you know besides cookies?

In addition to cookies, there are several ways to store data in a browser:

• LocalStorage — stores data as key-value pairs, accessible only on the client side, data persists indefinitely until manually deleted.

• SessionStorage — similar to LocalStorage, but data only lives within a single browser session (deleted when the tab is closed).

• IndexedDB — a more complex and powerful database in the browser, allows storing structured data, supports transactions and queries.

• Cache Storage (Cache API) — used for storing request responses, often used in PWA for offline access.

• Web SQL (deprecated) — an outdated API for storing data in SQL format, not recommended for use.

Example of using LocalStorage:

// Write data
localStorage.setItem('username', 'Ivan');

// Read data
const user = localStorage.getItem('username');

// Delete data
localStorage.removeItem('username');

These methods allow storing data on the client side without needing to send it to the server with each request.
