Question

How long is cool_secret accessible?

sessionStorage.setItem('cool_secret', 123);

• A: Forever, the data doesn't get lost.
• B: When the user closes the tab.
• C: When the user closes the entire browser, not only the tab.
• D: When the user shuts off their computer.

Answer 1

Answer: B

The data stored in sessionStorage is removed after closing the tab.

If you used localStorage, the data would've been there forever, unless for example localStorage.clear() is invoked.
