When should you use LocalStorage?

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 using localStorage a good idea?

Local storage is inherently no more secure than using cookies. When that's understood, the object can be used to store data that's insignificant from a security standpoint.

When should I use local storage vs session storage?

localStorage and sessionStorage accomplish the exact same thing and have the same API, but with sessionStorage the data is persisted only until the window or tab is closed, while with localStorage the data is persisted until the user manually clears the browser cache or until your web app clears the data.
