Limitation of localStorage

The localStorage allows you to store temporary, local data, which persists after you close the browser window, but it also comes with a number of limitations. The following are some limitations of localStorage:

• Local storage should not be used to store sensitive information such as usernames and passwords.
• Data stored in localStorage is not protected and can be accessed by any code. As a result, it is quite insecure.
• LocalStorage allows you to store a maximum of 5MB of data on the browser.
• The information is only stored in local storage on the browser and not in a server-based database.
• In localStorage, each operation is executed sequentially.

Advantage of localStorage

There are several advantages to using local storage. The first and most important advantage of localStorage is its ability to store temporary but useful data in the browser, which remains even after the browser window is closed. The following are some of the advantages:

• LocalStorage stores the data collected by the browser. The browser allows you to store up to 5 MB of data.
• Data stored by localStorage does not have an expiration date.
• The localStorage items can be removed by a single line of code, i.e., clear().
• LocalStorage data persists after closing the browser window, similar to items in a shopping cart.
• Furthermore, it has the advantage of being able to store more data than cookies.
