sessionStorage: don’t keep data when explorer closed
localStorage.setItem('token', 'Bearer xxxx') // k/v always be treated as a string; object will call toString()
localStorage.setItem('objKey', JSON.stringify(obj))
JSON.parse(localStorage.getItem('objKey')) // parse(null) --> null
localStorage.removeItem('token')
localStorage.clear()
