Why do we use local storage?

Question

Local storage provides at least 5MB of data storage across all major web browsers, which is a heck of a lot more than the 4KB (maximum size) that you can store in a cookie. This makes local storage particularly useful if you want to cache some application data in the browser for later usage.

Is local storage good to use?

If it's sensitive information or data that is better suited to be stored in the server, then it shouldn't be stored in Local or SessionStorage. But if you want your user to be able to toggle light or dark mode and have that state persisted, then LocalStorage is a good option!

When should I use browser local storage?

Local storage allows developers to store and retrieve data in the browser. The data stored in local storage will not expire. This means the data will persist even if the tab or the browser window is closed.

When should I use local storage vs session storage?

sessionStorage is similar to localStorage ; the difference is that while data in localStorage doesn't expire, data in sessionStorage is cleared when the page session ends. Whenever a document is loaded in a particular tab in the browser, a unique page session gets created and assigned to that particular tab.
