135. localStorage with expiration
medium - accepted / - tried
Also Safari's ITP actually deletes client-side script-writable storage after 7 days of Safari use without interacting on your website, and localStorage is included.
Unlike Cookie, localStorage doesn't expire.
In this problem, please create a localStorage wrapper with expiration support
myLocalStorage.setItem('bfe', 'dev', 1000) myLocalStorage.getItem('bfe') // 'dev'
after 1 second:
myLocalStorage.getItem('bfe') // null
localStorage is replaced with our own implementation to avoid security error. But the interface is the same, actually you don't need to care :)
