What are the differences between sessionStorage and localStorage in Vue.js?

In Vue.js, sessionStorage and localStorage are both part of the Web Storage API, but they serve different purposes. sessionStorage is limited to the duration of the page session, meaning data is lost when the tab is closed. localStorage, on the other hand, persists even after the browser is closed and reopened.

Can you give me an example of how to use sessionStorage in a Vue component?

Sure! You can use sessionStorage in a Vue component like this:

export default {
  mounted() {
    sessionStorage.setItem('key', 'value');
    const value = sessionStorage.getItem('key');
    console.log(value); // Outputs: value
  }
};

Is there a limit to how much data I can store in localStorage?

Yes, localStorage typically has a limit of about 5MB per origin, but this can vary by browser. It's best to check the specific limits for the browsers you are targeting.

When should I use sessionStorage instead of localStorage?

You should use sessionStorage when you need to store data that should only be available for the duration of the page session, such as temporary user inputs or state that doesn't need to persist after the tab is closed.
