Is it required to put await ahead of setItem ?

[kailashkumar210]

Is it required to put await whenever doing setItem something in AsyncStorage ?

what will be the impact if I do not write await, will it still save the data ?

You do not need await in order for setItem to start the write, but you do need it if your next line depends on that write having finished.

Example:

AsyncStorage.setItem('@token', token)
navigate('Home')

This will usually still save the data, but you're not waiting for completion and you won't catch write errors.

Safer version:

try {
  await AsyncStorage.setItem('@token', token)
  navigate('Home')
} catch (e) {
  console.error('Failed to persist token', e)
}

So the rule of thumb is:

• fire-and-forget write, result not important -> await is optional
• ordering / error handling matters -> use await

I would recommend await most of the time, especially for auth tokens, onboarding flags, drafts, or anything you read immediately afterwards.
