If the value is set, it will return the value, else it will return null

 interface SetOption {
  exp?: number; // Expiration time in second

storage.set("data", data, { exp: 60 });
// Before 60 seconds, you can get the data value
// After 60 seconds, if you call storage.get('data'), it will return null

console.log(storage.get('data')) // [1, 2, 3, 4]
