setItem() adds an item to the storage. Accepts a string as key, and a string as a value:
localStorage.setItem('username', 'flaviocopes')
localStorage.setItem('id', '123')
If you pass any value that’s not a string, it will be converted to string:
localStorage.setItem('test', 123) //stored as the '123' string
localStorage.setItem('test', { test: 1 }) //stored as "[object Object]"
