localStorage: Your Browser's Persistent Key-Value Store
localStorage is a simple dictionary saved in the browser that persists after the tab closes. Use it to save user settings like a theme. The footgun: all values are strings, so numbers and booleans need manual conversion, like parsing 'true' back to a boolean.
localStorage is like a simple dictionary saved in the browser that persists even after the tab is closed. It's a key-value store for strings, perfect for saving non-sensitive user settings like a chosen theme or language preference. The main footgun: it only stores strings. Storing an object requires `JSON.stringify()` and retrieving it needs `JSON.parse()`; forgetting this saves the useless string `"[object Object]"` instead of your actual data.
