Local Storage

Local Storage is a web browser API that allows websites to store key-value pairs of data persistently in a user's browser. It provides a simple, synchronous storage mechanism with no expiration date, enabling data to persist across browser sessions. Unlike cookies, it has a larger storage capacity (typically 5-10 MB per origin) and is not sent with HTTP requests.

Also known as: Web Storage, DOM Storage, window.localStorage, localStorage API, Browser Storage

Why learn Local Storage?

Developers should use Local Storage for client-side data that needs to persist between sessions, such as user preferences, form data, or application state in single-page applications. It's ideal for non-sensitive data due to its accessibility via JavaScript and lack of built-in security features, making it unsuitable for storing passwords or personal information.
