AsyncStorage.getItem() returns a single value AND a promise

Since storageGet returns a promise, you need to also use await anywhere you use it:

const value = await storageGet(key);

AsyncStorage saves data only as strings. You just need to use JSON.stringify() when saving and JSON.parse() when retrieving.

AsyncStorage.getItem('key')
.then((value) => {
  const data = JSON.parse(value);
  console.log('name is ', data.name);
});
