Web Storage API: Browser Key-Value Stores
Web Storage provides simple browser key-value stores: `localStorage` and `sessionStorage`. Use `localStorage` for data that persists across sessions, like user settings, and `sessionStorage` for data tied to a single tab.
The Web Storage API offers two simple key-value stores, `localStorage` and `sessionStorage`, a more intuitive way to save data than cookies. Use `localStorage` for data that persists after the browser closes, like user settings. Use `sessionStorage` for data tied to a single tab's lifetime. The main footgun is that the API is synchronous; every read or write blocks the main thread, which can freeze your UI with large datasets.
