When I use AsyncStorage.getItem() to retrieve the value (an email address) of a specified key, it returns a Promise object as indicated in the documentation. The value appears in object like so:
{
_45: 0
_54: null
_65: "[email protected]"
_81: 1
}
Can I reliably access this value by calling obj._65 or is there another way to accomplish this?

To get promise value in React and JavaScript, we can use await . to create the getAnswer function that calls fetch with await to get the response data from the promise returned by fetch . Likewise, we do the same with the json method. And then we call setAns to set the value of ans .
Async Storage can only return string data, so in order to use number or object we have to first converts it from string . To get value from asyncstorage, React native asyncstorage provide getItem() method, it will expect storage key and return value .
Deprecated. Use one of the community packages instead. AsyncStorage is an unencrypted, asynchronous, persistent, key-value storage system that is global to the app. It should be used instead of LocalStorage.
AsyncStorage return a promise. you can use .then for get value
exemple:
AsyncStorage.getItem('key').then((keyValue) => {
console.log(keyValue) //Display key value
}, (error) => {
console.log(error) //Display error
});
